Here are pictures of my new canvas sock made from a $12.00 painter's drop cloth that I bought at Menards. If I did it again, I would get a canvas drop cloth from Harbor Freight because their canvas looked nicer.
I put a zipper in and installed 3 pockets in the side near my head.
Now all I need is some cold weather to try it out.
Pics were taken in my basement, which is a mess. Last pic is the end of the sock, turnd 90 deg. counter clockwise.
