Hi everyone. If you're looking for PVC for molds, especially if looking for 6 inch or larger (i.e. your name is Cartier or Wayne or...LOL) You might want to check with your local public-works department. They often have sizes up to 20 inch which are cut-offs or lengths with broken ends, etc, that they just might let you have a chunk of. It never hurts to ask, and they always get a warm, fuzzy feeling from giving away something they were going to throw away eventually anyway. OMC
