It's sculpey clay, which is polymerYeah I did! Once I get a job I'll definitely consider commissioning her for one of my OC or something. Her villager shelf is so perfect (especially the Merengue & Molly, I probably went into a fit just looking at it)
She uses wire too so I suggest noting that down like someone else did earlier, op. Though I don't think she uses polymer, she just uses regular ol' clay and paints over it.
She uses apoxie (air dry clay) for finer details.
