On our way out the door to the farmer's market last weekend, I remembered to bring a bag with me (a rarity). I brought what I thought would be suitable, one of these, but it didn't cut it. We filled that thing up in no time. It made me realize that I don't really have any big bags. Yes, I have big purse type bags, but not any BIG market bags, as in extra large bags.
I went to my sheet stash because that just seemed right. Oh, my beloved sheet stash. I'm so happy I'm no longer afraid to cut into them. I skipped the interfacing opting for floppy and easy folding. It's also fully reversible.
