Trying the previous example but slightly bigger and not in a ball (like a did before) but concave...so when the plaster is thrown in and wiped over I'll have a half hole-y half solid blob-ish shape. Hopefully.
Sadly the damn thing broke when getting it out of the mold. Someone in my class suggested I add water based PVA to strengthen it, keeping in mind it would take a little longer to dry, and maybe some rock dust. Well I only had the PVA, added that and it turned the plaster more brittle. The bloody stuff crumbled!
But my idea worked, this is what I was after. I'm loving it!
