Ok guys I am on day 13 from a back surgery and stuck at home going crazzzyyyy. So I decided I could make these up with no effort at all.
First I found some couch cushions(2 normal size) set out for the trash(4 weeks ago). Then I had some burlap bags I got for free from a tree yard(past summer). And some contractor trash bags.
1. I took the foam out of the cushion and cut it the size of the burlap bag.
2.I put the foam in a trash bag (for waterproofing help)and wrapped it up and taped it(duct tape)
3.Put it in the burlap bag and sew it shut.
total cost about $2.00 in trash bags I had.
I was able to make three larger ones(14"x 30" x 5") and a small one for throwing around and shooting(14" x 8" x 5"). Hope you like them.
