So basically. I sketch, and sketch till I find a design I like, try to find an appropriate size... and use that as reference/ a stencil for my clay. Then after they dry, each are hand painted with acrylics. Then sealed in waterproofing spray. They have stood up to shower room steam for me, sweat, rainy days, soaking wet hair... I would not advise. BUT! Saying they are resilliant.
