I'm not saying anyone should use enamels in their beads. And I am saying to use a mask and proper ventilation if you do. I do use enamels, so here's one little thing I've learned about them that has a cool look. Make your core bead. Roll in enamel- white works well. Wrap with a nice lightly colored transparent. That's it! You can see how cool it looks in the pics. No need to fully encase. I think it actually looks more interesting if you don't.
By the way, I don't care how many people say to do it, I DO NOT recommend putting your enamel in a shaker or sifting it onto your beads. Talk about some airborne micro particles that you can breathe! Ugh!
