Hey everyone,
If this question has been asked before please point me in the right direction, I used the search and didn't find an answer. I just started making beads last week. I am having issues with my bead release. When I heat my mandrel the release cracks and either goes flying off or gets all over my bead. Any ideas on what I am doing wrong? I have cleaned my mandrels and used a low grit sandpaper and that hasn't helped. I also tried to flame dry them but got the same result as air dry. Thank you in advance
