Materials i use white cement Australian builders brand, Australian builders oxide, bondcrete, water, glad wrap on both moulds, plastic bag to make sure cement doesnt get through box and a stick i found in back yard for easy removal of the inner mould. First i made a box out of card board you could use wood and nail it together then i put a plastic bag in box mixed some sand and cement wrapped the hide in gladewrap(clingfilm) place into the cement and weight it down with something even and not to heavy try make the cement even around the mould so you get a hide with a flat bottom let it dry then do simular for the inner mould place glad wrap ontop of hide and pour enough cement in mould so its even with the other moulds lip place a stick in the center so you can remove easy. I found it easyer to make the cement dryer when your making the mould and make sure you gladwrap all moulds before you begin then you remove the inner mould staight away. If you find the cement is not holding just leave in until it is a little set cause there is a chance when you remove the mould you could break the new hide from the mould getting dried into the hide making it difficult to remove resulting in breakage of the hide. I also forgot add bondcrete to the hide mixture just for the extra strength. The bag of cement is like $16
