"I didn't use silicone for shoes, I used latex - but I guess silicone would work too. I do like fabric clothes for many reasons.  There are difficulties with scale - fabric doesn't behave the same when it is too small, you get thick…"

"Yeah,I have a very "crude" and simple" sketch.All the stuff I drew up over the weekend is in the recycle bin.If you wanted to braze to the ball,wouldn't you just need to  orient the ball(after you braze it in with a rod) to…"

"I have been thinking for a 3/32 ball joint the rod can be soldered to the side of the ball instead of drilling a hole in the ball. Got pictures of what your trying to do? "

John Polacchi replied to Danny Samuels's discussion Is Flexible Urethane Foam an Option?
"Nick,wouldn't that also depend on how dense the foam is and if you are just using it to fill in "large" body parts(like thighs or the upper torso) and to help reduce the overall weight of the puppet?"
