Hello, I'm just starting to get into molding and casting and have been reading ALOT on it though I’m still a little unclear on some things, I’m sure parts of this will become clear when I actually buy some stuff and start playing with it but I like to get as much info before jumping in. I’m making a costume which has rather large horns, which I have sculpted out of oil based clay and would like to cast into a much lighter and slightly more flexible material. I’m not really sure what to cast the horns in... Does anyone know of any good tutorials or books or videos that might go into more depth into large horn making?
Thank you guys so much I could use all the help I can get!

Smooth-on has alot of video tutorials and also has a whole section on taxidermy/horns. Go check it out. You may find what you are looking for.

Definately check out Smooth-on and Polytek. Go to www.theeffectslab.com forum as well. They deal with all kinds of special effects stuff.
