1. Make sure your doll is completely dry before powdering. Also, sometimes a rough doll seam can cause the powder to stand out more than other parts of the body.
2. TPE doll, baby powder by hand. I think maybe it was just the oil from my own hands causing it to clump. Doesn’t seem to be happening anymore.
3. Get a nice large powder makeup brush. They are not expensive and are far better for evenly distributing powder on your girl’s skin than rubbing it in by hand.
