Picture of Make your own bones for Halloween
Ok Its getting close to Halloween, and thats my favorite holiday to decorate for. I really like skeletons and such, but im really not into obtaining real bones (at least not my own) and the fake ones can cost a good bit. So I decided to make my own. Now this instructable will show you how to make the molds so you can make your own bones over and over. Im not going to show you how to make an entire skeleton, but with these steps you should be able to make the rest of the molds on your on.

By the way, this is my first Instructable so if you find it interesting, I would truely appreciate any comments.

Step 1: Gather Materials

Picture of Gather Materials
Ok, theres not too much needed to make a mold.

~Object to make a mold from

~Mold compound - in our case we will use liquid latex

~Plaster cloth - used to make a frame for our latex mold

~A clean, Taclon brush. - used to "paint" on the latex. Dont use a regular paint brush. Ill explain later.

~Clay - used to make a base for the mold

~Plastic food wrap

Nice instructable. Like you said in step 4 be careful with the plaster, mother mold. Just like a matrix mold if there is not enough latex/silicone/flexible medium between an undercut of the original/casting then you can have the mold seize. Use thicker layers to help even out the undercuts, which will help when pulling the castings made of a hard medium. Sometimes its good to put a channel or two for the mother mold of plaster to make sure the latex sits correctly. I'm planning an RTV silicone instructable to do the same thing but for larger undercuts(because we can't all afford shore 20 pourable silicone/polyurethane). We will see if I ever get around to it :P

Hey Cthulu I always wanted to ask; was The Bloop really made by you?
Cthulu (author)  finfan76 years ago
No, that sound was produced by the deep ones. Had any one gotten close enough to hear me, I would have just bitten their head off.

Cool. Hey, as an afterthought, how much did you get payed for your role in Dark Corners?

When you are as evil as I am, money has no use. I did require three live sacrifices per scene though.
