Assam ASSEB HSLC Garment Designing cheat sheet

Garment design has two branches: structural design (shape, cut, construction) and decorative design (applied surface ornamentation such as embroidery, printing and trims).

The apparel production sequence is design → pattern making → sample/marking → spreading and cutting → stitching/assembly → finishing → inspection → packing and dispatch.

Industry sectors are distinguished by volume and method: haute couture (made to individual measure), ready-to-wear (standardised size ranges) and mass/bulk production (large-volume, graded size sets).

A design brief fixes five parameters before drafting: end use, target consumer (age, gender, size range), season, fabric and price point.

Design development stages: inspiration and research → croquis/sketches → flat technical drawing → specification sheet → pattern and toile (muslin) sample → fit approval → production pattern.

The fashion cycle runs introduction → rise in acceptance → peak (mass copying) → decline → obsolescence; classic styles stay in the maturity phase for years.

The sampling chain is proto sample → fit sample → size-set sample → sales/photo sample → pre-production (PP) sample → top-of-production sample.

A tech pack/spec sheet carries measurements, fabric and trim details, construction notes, colourways and tolerance limits; it is the contract between design and production.

Measuring tools and uses: tape measure (body and long curves), seam gauge (short repeated widths such as hems and tucks), L-square (90° corners), French curve (armholes, necklines), hip/set square (shallow curves).

Marking tools: tailor's chalk and chalk wheel for temporary marks, tracing wheel with carbon/dressmaker's carbon for transferring pattern lines, tailor's tacks for marks needed on two layers.

Cutting tools: bent-handled shears keep the blade flat on the table; pinking shears cut a zigzag edge to limit ravelling; seam ripper removes stitches without cutting fabric; rotary cutter needs a self-healing mat.

Sewing machine needle rule: finer needle for lightweight fabric, larger needle and longer stitch for heavy fabric; a blunt or wrong-size needle causes skipped stitches and pulled threads.

Machine parts to identify: feed dog, presser foot, needle plate, bobbin case, tension dial, take-up lever, reverse lever; upper tension is adjusted only after threading and bobbin tension are correct.

Ironing vs pressing: ironing slides the iron over the fabric, pressing lifts and lowers it; pressing is done over a pressing cloth on wool and synthetics to avoid shine.

Safety rules: keep fingers behind the needle, unplug before changing needles or cleaning, never place pins in the mouth, keep shears closed and pointed away, keep the work area free of trailing cords.

First aid for a needle prick: let the wound bleed briefly, wash with soap and water, apply antiseptic and cover; report any injury and check machine guarding afterwards.

Fibre classes: natural (cotton, flax/linen, jute, silk, wool) and man-made (regenerated such as viscose/rayon, and synthetic such as polyester, nylon, acrylic).

Cotton: absorbent, strong when wet, takes dye and heat well, creases easily, shrinks unless pre-shrunk; burns with a steady flame, smells of burning paper, leaves grey ash.

Silk: smooth, lustrous, strong but loses strength when wet, damaged by strong sunlight and perspiration; burns slowly with a hair-like smell and leaves a crushable black bead.

Wool: crimped, elastic, warm, absorbs moisture without feeling wet, felts with heat + moisture + friction; burns with a slow sputtering flame, hair smell, crushable dark ash.

Polyester and nylon: thermoplastic, low absorbency, quick drying, strong, heat-sensitive; burn with a melting shrivel, chemical smell, hard bead that will not crush.

Yarn count systems: direct systems (tex, denier) give weight per fixed length - higher number = coarser yarn; indirect systems (cotton count, metric) give length per fixed weight - higher number = finer yarn.

Yarn types: staple (short fibres twisted together, fuzzy surface) versus filament (continuous, smooth); single, ply and cord yarns; fancy yarns include slub, bouclé, chenille and spiral.

Weave structures: plain (one-up-one-down, firm, least lustrous), twill (diagonal, 2/1 or 3/1, drapes well - denim, gabardine), satin (floats give lustre and a smooth face), plus pile, jacquard and dobby.

Knits versus wovens: wovens use two yarn sets (warp and weft) and have grain and selvedge; knits interloop one yarn set, stretch, and need ball-point needles to avoid ladders.

Key horizontal measurements: bust/chest at fullest point, waist at natural waistline, hip 18–23 cm below waist (about 20 cm for adults), shoulder width tip to tip, neck girth at base.

Key vertical measurements: nape to waist (centre back length), front waist length (shoulder-neck point to waist over bust), skirt length (waist to desired hem), inseam (crotch to ankle), outseam/side seam (waist to ankle).

Sleeve measurements: sleeve length is shoulder point to wrist with the arm bent; also record upper-arm girth, elbow girth and wrist girth for fitted sleeves.

Ease = garment measurement − body measurement. Fitting ease allows movement; design ease creates the intended silhouette; woven fabrics need more ease than knits.

Standard ease guides for adult wovens: about 5–8 cm at bust, 2–3 cm at waist, 5–7 cm at hip for a fitted garment; add more for loose styles.

Measuring rules: stand the subject straight and relaxed, tie a tape at the natural waist, keep the tape snug but not tight, measure over light clothing, record in centimetres consistently.

Size charts grade between sizes by fixed increments (commonly 4–6 cm at bust and hip, 4–5 cm at waist); each size is a body-measurement range, not a garment measurement.

Children's sizing advances by height and age bands with smaller increments than adult grading; children's charts also allow extra ease for growth.

Pattern-making methods: drafting from body measurements (flat pattern), draping on a dress form (toile then trueing), and commercial pattern alteration; all produce a paper pattern with grain, notches and seam allowance.

Drafting sequence for a bodice block: rectangle of bust width × nape-to-waist length → mark waist, bust and chest lines → back neck and shoulder → armhole curve → bust dart → front neck, shoulder and armhole → true seams.

Dart principles: a dart points to the fullest part of the body (bust point, shoulder blade, elbow); its legs are equal and it is stitched from the wide end to the point, never past it.

Seam allowance standards: 1 cm on most seams, 1.5 cm on curved and armhole seams, 4–5 cm on hems; add these after the block is fitted, since blocks are drawn without allowance.

Grain line must run parallel to centre front/back; the pattern's straight-grain arrow is aligned with the selvedge when laying out.

Grading = systematically increasing or decreasing a pattern through a size set using grade rules; the base size is kept and other sizes are moved by fixed increments at each landmark.

Grade rules move points, not shapes: neck, shoulder, bust, waist, hip and length each get their own increment; care is needed at armhole and crotch points where two increments meet.

Pattern symbols: notches (matching points), dots (dart points and placement), grain arrow, place-on-fold bracket, buttonhole and pocket markings, and the cut/stitch line distinction.

Fabric has three grain directions: lengthwise/straight grain (warp, parallel to selvedge, least stretch), crosswise (weft) and bias (45°, greatest stretch and drape).

Layout types: open (fabric opened full width), folded (double layer for pairs), and combination; choose the one that uses the least fabric while respecting grain and nap.

Nap and directional fabrics (corduroy, velvet, satin, printed one-way designs) require all pattern pieces laid in one direction - a with-nap or one-way layout.

Marking methods: tailor's chalk, chalk pencil, tracing wheel with carbon, tailor's tacks and thread marking; marks go on the wrong side unless a placement is meant to show.

Cutting rules: cut on a flat surface with long firm shears strokes, keep the lower blade on the table, do not lift the fabric, and cut notches outward, never inward into the seam.

Fabric estimation depends on garment style, fabric width (usually 90 cm or 112–150 cm), nap, size and layout; wider fabric reduces required length for most garments.

Checks before cutting: grain lines parallel to selvedge, pattern pieces within the fabric, nap direction consistent, all pieces present, seam allowances included.

Cutting accuracy affects fit: a piece cut off-grain will twist after washing, and a stretched bias edge will hang unevenly; staystitch curved edges soon after cutting.

Plain/seam types: plain seam (pressed open or to one side), French seam (encloses raw edges, for light fabrics), flat-fell seam (strong, double-stitched, for jeans and shirts), lapped and welt seams.

Seam finishes for raw edges: overcasting, zigzag, overlock/serging, bias binding, turned-and-stitched, pinking and Hong Kong finish.

Stitch classes: straight stitch (seaming), zigzag (neaten and stretch seams), blind hem stitch (invisible hems), buttonhole stitch, and triple/ stretch stitch for knits.

Stitch length and tension: shorter stitch for fine fabric, longer for heavy; balanced tension shows equal loops top and bottom - loops underneath mean upper tension is too loose.

Assembly order for a basic bodice: staystitch → darts → shoulder seams → neckline finish → sleeve setting → side seams → hem; pressing follows each step.

Sleeve setting: ease the cap between notches with two rows of long stitches, distribute fullness over the cap, and match the sleeve notch to the shoulder seam.

Fastenings: button and buttonhole (buttonhole length = button diameter + thickness), zip (centred, lapped or invisible), hooks and eyes, press studs, and Velcro.

Hem finishes: turned, blind, rolled (fine fabrics), faced, and bound; hem depth varies with garment - deeper on skirts, narrower on sleeves and children's wear.

Elements of design: line, shape/form, colour, texture, space and size; principles: balance, rhythm, emphasis, proportion, harmony/unity and scale.

Line direction effects: vertical lines lengthen and slim, horizontal lines widen and shorten, diagonal lines add movement, curved lines soften.

Balance is either symmetrical (formal, mirrored) or asymmetrical (informal, visually weighted); garment centre front and back act as the axis.

Rhythm is created by repetition, gradation, radiation, transition and opposition - for example repeated pleats, graded tucks or a border print.

Proportion concerns the relationship of parts to the whole; the golden-mean (roughly 3:5 or 8:13) division is a standard guide for jacket length and yoke placement.

Emphasis (focal point) is created by contrast, colour, texture, trims or placement; it should be limited to one dominant area per garment.

Texture affects apparent size: shiny, stiff or bulky textures enlarge; matte, soft, fine textures reduce apparent bulk.

Harmony/unity means all elements support one theme; a garment fails unity when trim, colour and silhouette compete rather than reinforce.

Colour dimensions: hue (name), value (lightness/darkness), saturation/intensity (purity); tints add white, shades add black, tones add grey.

Primary colours are red, yellow and blue (pigment); secondary colours are the two-primary mixes; tertiary colours mix a primary with a neighbouring secondary.

Colour schemes: monochromatic (one hue, varied value), analogous (adjacent on the wheel), complementary (opposite, high contrast), split-complementary, triad and accented neutral.

Warm hues (red, orange, yellow) appear to advance and enlarge; cool hues (blue, green, violet) recede and reduce apparent size.

Colour theory for garment design: light values enlarge, dark values reduce; vertical colour blocks lengthen; a contrast belt or yoke draws the eye to that area.

Surface ornamentation methods: embroidery (hand and machine), appliqué, patchwork, printing (block, screen, digital), tie-and-dye, batik, quilting, beadwork and mirror (abhala) work.

Embroidery stitches to name: running, stem, chain, satin, blanket, feather, cross and lazy daisy; each gives a different line weight and texture.

Ornamentation placement must respect the design principles - border prints at hem or sleeve, motifs at yoke or neckline - and must not distort the grain or fit.

Assam's signature silk is muga, a golden-coloured wild silk from Antheraea assamensis, produced mainly in the Brahmaputra valley; it is a Geographical Indication product.

Eri silk (from Samia ricini) is a non-violent silk - the cocoon is spun after the moth emerges - and is known for warmth and a soft, wool-like texture.

Pat silk is a white/cream mulberry-type silk of Assam, valued for its lustre and used in mekhela chador and sarees.

The mekhela chador is the traditional two-piece Assamese woman's dress: the mekhela (skirt-like lower drape) and the chador (upper drape), often with a riha.

Bihu dance costume uses the mekhela chador with a riha and traditionally the gamosa; the gamosa is a white cotton cloth with red border and woven motifs, used as a mark of respect.

Assamese weaving centres and motifs: Sualkuchi (silk weaving), woven motifs such as kingkhap (butterfly), mina, gos and geometric borders; the jaapi (bamboo hat) and xorai are cultural symbols.

Other Indian traditional textiles: Banarasi brocade (Uttar Pradesh), Kanchipuram silk (Tamil Nadu), Paithani (Maharashtra), Bandhani (Gujarat/Rajasthan), Chanderi and Maheshwari (Madhya Pradesh), Pashmina (Kashmir), Phulkari (Punjab).

Regional costumes to know: dhoti and kurta, saree, salwar kameez, lehenga choli, lungi, and the Assamese mekhela chador; each reflects climate, craft tradition and occasion.

Care label symbols: washtub (washing, with dots for temperature), triangle (bleach), square with circle (tumble dry), iron (dots for temperature), circle (dry clean) and the cross meaning do not.

Washing rules: sort by colour and fabric, turn garments inside out, use the recommended temperature, avoid overloading, and dry in shade to prevent fading.

Cotton tolerates hot water and a hot iron; wool needs cool water, mild detergent, flat drying and steam pressing; silk needs gentle hand wash and low heat; synthetics need low heat and no hot tumble drying.

Quality control points in production: fabric inspection (holes, shade variation, bowing), cutting accuracy, stitch density, seam strength, measurement check against the spec, and final inspection before packing.

Common defects: skipped stitches, seam slippage/puckering, shade variation between panels, off-grain twisting, uneven hem, missing trims and incorrect measurement beyond tolerance.

AQL (acceptable quality level) sampling is used for final inspection instead of 100% checking; a lot passes when defects found in the sample are within the agreed AQL.

Entrepreneurship basics for garment units: market survey, product costing (material + labour + overhead + margin), licensing/registration, branding, pricing and a distribution channel.

Costing formula: total cost = fabric consumption × rate + trims + labour + overheads; selling price = total cost ÷ (1 − desired profit margin), and break-even quantity = fixed cost ÷ (price − variable cost per unit).
