I bought some of these after my first few weeks making my sons lunch. I was surprised how many plastic bags I went through!!  These are well made and a good price for quality. I feel so good about using them.

Eliminate the need for plastic baggies by enjoying your lunch on these cute sandwich wraps. Made with cotton fabric and lined with a piece of flannel-backed vinyl table cloth, these 12" X 12" wraps will keep your sandwich fresh and then give you the perfect little portable placemat to eat on. The cute gingham check gives a nostalgic feel--like grandma's house or a neighborhood picnic. And the best part: they are completely washable and reusable!
Just place your sandwich in the center, fold the side corners in and tuck around your sandwich, then fold up the bottom, fold down the top, and secure with the velcro!
