Mokume gane. It’s the polymer clay technique everyone loves but hates to pronounce. So here it is: mah-KOO-mah GAH-nay. Not to be confused with “hakuna matata,” OK?
Polymer clay actually borrowed the mokume gane technique from a metalworking technique used by Janpanese sword makers.
I’m better versed in how it’s done with polymer clay than in swords. I’ll be teaching one method, as illustrated in the boot, in my Spring Lifetime Learning Institute class.
If you’d like to try your hand at it, here’s a Mokume Gane Bead tutorial from Polymerclay web.
