Sequin fabric is made by sequins being sewn onto a mesh or chiffon background. Simple garments are the best collarless jackets, shift dresses and pencil skirts avoid pockets, pleats and gathers.
When cutting out treat as it has a nap. pattern weights are ideal, an old sheet placed under your cutting table will make life a little easier. Cut out wit old scissors as sequins will nick the blades. Cut fabric single thickness with at least 1inch/2.5cm seam allowence.
Sew with 90/14 needle though do have a few on hand as sequins will dull the needles. There are are couple of ways of sewing up the seams, you can pull the sequins out of the allowences, be careful not to cut the threads and keep some sequins to one side, then you can replace any damaged sequins or bald spots near the seamline. Use a zipper foot as it will glide over the sequins easier than a regular foot. The other way of sewing the seams is to fold back the seam allowence on either side of the seam butting the folds and sew together by hand using a ladder stitch, this lets the sequins from each piece overlap each other which will force the seam allowence open, helps to camouflage the seam.If this method is use add a stable lining and you may want to remove some of the sequins on the inside to prevent them rubbing on the lining.
Stitch length 3mm, finger press as the iron will dull the sequins, hence use a sew-in interfacing. Face the hems with a smooth woven fabric.
Major tip...allow three times longer to sew with sequins than any other fabric.
