Has anyone used holographic thread with success? I tried it on a sample piece before I tried it on a quilt. Even though I followed the instructions given to me by the quilt shop where I bought it, I could not get it to sew more than a few stitches without it breaking. On the second try, it wouldn't stitch at all. Help! I used metallic on the quilt I'd intended to use the holographic thread on instead. It only broke once during quilting. Help.
