kwhite - there is an outhouse at hubby's hunting camp. They keep their rolls in a big old potatoe chip can. I think the chip makers took their potatoe chips to the local farmer's market in these cans in the old days. I think if I would make a privy bag to hold their t-paper, they would laugh my husband out of camp! Plus, the next time we were at camp, we would find that someone had stolen it!
The bags look like they might be about 18" square. Supersize a block maybe? Hey, maybe instead of hiding an extra roll somewhere close to the toilet here at home, I can make a bag and hang it on the wall nice and handy!
