I'm not a big fan of metallic, but I did make a Christmas quilt using one of the metallic precuts. That was an accident, didn't realize it was metallic when I ordered it. It came out nice. The sparkle stuff I dislike immensely. I made a dog bandanna once for my Great Dane that had that sparkle stuff on it. It took weeks to get it off my ironing table, and I still find bits of sparkle where I don't want it. I think the metallics and sparkles are made better than tthey used to be made, seem to hold up better when washed, and don't shed like they used to. But I still think a little goes a long way when incorporatting metallic in my quilting.
