Beads and Metalsmithing Supplies
There are several steps you can take to increase durability for those Miyuki labels "attention is required".
One step is to spread beads out and spray with Krylon.
Brick stitch earring makers will often use clear nail polish to coat their finished earrings to both stiffen the beadwork, and protect bead finishes..
Personally, we prefer to use these finicky beads in projects where they do not come in contact with skin, or in areas where friction is less likely. If you are creating an heirloom piece, use only the beads that are colorfast and finish-fast.
