I bought a cookie sheet from the dollar store and covered it with paper. I made the grid on white cardstock. I used so many different stamp sets I'm not sure I could name them all! To create it I looked around in what I had in paper, stamps, and accents and came up with the designs. Each day is attached to a craft jar so you can put a little goodie inside. I put a few pieces of candy and my kids are happy. The craft jars attach to the cookie sheet with a magnet.
