When I was room mother for my son's first grade, their teacher was getting married. I decided a quilt from the kids would be something she'd always remember. I bought (with their money) white cotton and some "fabric" markers and cut squares for each child to draw a picture and sign it. I took them home, added sashing and put the quilt together. She was so surprised; and to this day, she still has the quilt. That was about 32 years ago.
