|(Note these are not tips for regular sequin fabric, but the kind with the sequin dots glued on).
I've been sewing a lot of dance costumes lately made from the dreaded, but oh so sparkly stretch sequin dot fabric. There are a few things I've found to keep me from going crazy while i'm sewing it.
A quick note on cutting- I only use a rotary cutter at this point (to save my wrists and hands) And I find it's especially helpful when dealing with Sparkle Dot fabric
1.) Use top stitching or leather needles, preferably Shmetz or a non-singer brand. (I don't know why, but even my singer machine does not prefer singer needles) I usually go through 1 or 2 of these while making a garment.
2.) Use high quality thread. Cheap thread will make your life THAT MUCH HARDER. It's worth the extra cost to get thread that won't drive you crazy, and this is pretty much true for sewing anything, but especially this stuff.
3.)Got Lube? I've tried different kinds of paper on top and underneath the fabric while sewing, but the best trick i've found to keep the glue from the dots off the needle is lubrication. Water based Lube is great for this. Mineral Oil works in a pinch too. Just put a TINY drop on your finger and rub the needle with it. I have not had a problem with this gunking up my machine or staining the fabric. You'll probably need to do this several times as you are sewing.
4.) MOVE SLOW. A slow, even pace works best when it comes to sewing Sparkle Dot. If your machine is going too fast and heats up, the dots come off sooner. They are only glued on. Take your time.
5.) Any time you change your stitch length or go from a straight stitch to any kind of decorative stitch, RE-THREAD your machine. This will help minimize the problems with stitch tension that this fabric can create.
6.) Back it with something soft. Stretch sequin dot is really scratchy on the inside. I use a very lightweight jersey fabric to act as a liner. The leather or top stitching needles seem to work ok with this as long as your sewing through the layers of seguin and this. However, if you're only sewing jersey (before you attach the lining to the sparkle dot), ballpoint needles are the way to go.
Hope this helps! Happy sewing. Sparkle! Sparkle!
