Sewing Pattern - Shopping Cart Support Cushion and Portable High Chair for Baby
Universal Shopping Cart/High Chair Cover (with pattern and tutorial)--I'm not so much worried about the germs, but when Olivia was a baby and couldn't sit up in the shopping carts yet, it was so easy to just lay down a blanket and let her hang out in that part of the cart anyway. I think this would be easier and probably get a lot of use. Especially since it would also be good when the baby's big enough to sit up, but still little enough to fall over a lot. :)
