like most of you archers out there im on a budget. i already own a 3D target and have used an old turkey decoy filled with expandable foam for another as well as have used the old carpet idea and reshuffled my layerd block. But Id like to get a little more serious about making 3D targets and possibly make something a little larger than a turkey decoy. maybe something like a fox or pig but eventually get into making full size targets of all sorts. Ive been searching all over for ideas and have come across several good types of foam but it seems like i am going to have to make a mold for this project... which would be fun and all but im not sure if it would save me any money. So if anyone has any expierence building their own 3D targets with or without a mold and what their favorite kind of foam is let me know. Thanks.
