Loyal readers know the initial school we started the year with did not go well. Thirteen days there before we started anew (and the tuition litigation continues, they let their attorney go, hired another and asked for a continuance). So when this frugal Mama started taking English Muffin sandwiches to work, my frugal overdrive was in full-force. I was not going to spend another $20 on those reusable bags. Inspiration hit one morning after reading a Little House on the Prairie book -- Just use a cloth napkin! And so I do. Purchased used from a thrift store, the cost is less than $1. But I use the ample supply we already have on hand. If I were a crafty frugal Mama, which I am not, I'd probably stitch up the sides and add Velcro. My 1800s approach works just fine.
No need to purchase or drive to a store. No new materials used or shipped. It's good for the earth, wallet, and body! Happy frugal living.
