Usually I've been using just the thinner zips which don't have a hard plastic part, but 2 of my costumes in progress have needed the thicker metal, jacket zips and I've had alot of trouble sewing over the plastic part at the end.
I've tried using a jeans needle but I've broken 2 already, lol. I wasn't sewing fast, and the 2nd time I tried just to do it manually on the sewing machine as well. Is it just my sewing machine or is there another method/needle I can try? I also tried poking it through by hand but it kind of bent the needle as well.
I'm using a Janome MyStyle machine, if that helps any
