@szjulka you can just cut them. I like cutting them really short, I know other people cut them and put nail polish but I've never done that and my bracelet turn out fine. Hope it helps!
@abana1234 No you can not i suggest you o watch Masha knots on youtube or Racoon here on bracelet book. She will help you to understand how to make bracelets and other little things you can do to make your bracelets better
