how can I make concrete molds ?
Is there any info on making concrete molds ? I was wondering about taking a stuffed animal and spraying it with a rubber type solution ( is there such a thing? )or almost anything that could be sprayed all over like a coating and after the coating stuff drys I would like to peel or cut it off for use as a mold that I could fill with lite weight concrete,or something .
can anyone help with this ?
