I was looking online to see the variety of these beads and came across an interesting website that has a tutorial about how to actually make what they call "Fantasy Beads. The example here has a whole galaxy of swirls and colors inside the bead.
To make the beads, they use products called Embellished paper beads with OPALS © embossing enamels and Fantasy Film, as well as paper scraps, a heat gun, wooden skewers, glue and a soldering iron.
The site has a step by step guide on how to make these lovely beads. You can view the fantasy bead making tutorial here.
Interested in other ideas about how to make interesting one of a kind jewelry or beads? They also have a whole range of tutorials, including making jewelry from DVDs and CDs, making art glass pins, and using embossing enamels. The finished products are amazing.
