One of my Prosser Farmer's Market customers is going to be a grandma for the first time. Her daughter is a germ a phobic and wanted a changing mat that she could stash in her diaper bag. Sew, this morning, I played a little and came up with this! I quilted 2 one-yard pieces of fabric, cut it in half and rounded the corners. Two mats measure ~22" x 29", It is double sided, rolls up and ties into a nice neat mat!
