We have been doing glitter flake vinyl for two years now and never had any issues. Around November, we started having customers complain that the fleece was pilling really bad and they had fuzz balls all over. It has gotten so bad that we have suspended use of it on fleece materials until we figure out what is going on. We have sent in sweatshirts into Sanmar to see if it is the sweatshirts themselves, but I suspect the glitter flake has become more coarse causing this issue. I have heard several people have this issue so it is not isolated to us. Anybody out there dealing with it?
