Machine Embroidery and Finishing Techniques

What this domain tests

This domain tests your ability to set up a machine, choose stabiliser and needle, control tension and hoop tension, and finish embroidered goods cleanly. Questions may describe a fault such as looping underneath or puckering and ask for the likely cause.

Core rules

  • Machine types: free-motion embroidery uses a dropped feed dog and darning foot; computerised machines follow a digitised design; multi-head industrial machines produce repeats. Stitch types include running, satin, fill and motif stitches, usually built on an underlay.
  • Stabilisers: tear-away for stable woven fabrics; cut-away for knits and stretch; wash-away for sheer fabrics, lace and toppings; heat-away for sensitive surfaces. Hoop the stabiliser with the fabric, not separately, and avoid stretching the grain.
  • Needles and thread: an embroidery needle (often 75/11) has a larger eye and scarf; use 90/14 for heavy fabrics or dense designs. Top tension should be adjusted so the bobbin thread does not show on the face. Loops or birdnesting underneath usually mean the top tension is too loose, the bobbin is uneven, or the machine is not threaded correctly.
  • Finishing: trim jump stitches, remove stabiliser, press face down on a towel, do not iron directly over raised or metallic work, check for stains, and package flat with tissue.

Worked example

A dense floral design on a cotton jersey T-shirt puckers. Choose cut-away stabiliser, a water-soluble topping, a 75/11 embroidery needle and a slightly reduced stitch density. Reasoning: jersey stretches, so tear-away alone lets the design distort; cut-away supports the knit; topping stops stitches sinking into the loops; reduced density limits bulk. Hoop gently: stretching jersey causes wave marks after unhooping.

Traps

Hooping fabric too tightly and causing distortion; using tear-away on stretch knits; ironing the right side directly; ignoring a bobbin case that is not seated; and removing all stabiliser from a sheer fabric where support is still needed.
