As all of us stitchers know, using metallic thread can be difficult, especially (for me) when it frays at the end and keeps slipping off the needle. But I've found a way around it:
I use the loop method. I take the ends of the thread and tie a knot an the end. I find it does not fray, the know doesn't make the holes bigger and it's going as well as regular thread.
When I want to anchor the thread at the end I just cut off the knot first.
Try it out, and god forn=F8jelse (good luck)
