This is what we did. First I found an inexpensive frame at Target. I meant to get out to IKEA, but didn't have time. Take out the glass and fit a background paper in the frame.
Now if you go to the link above from the Family Fun website, you'll see theirs is so much cuter. That's why I think if you start with new crayons it would work better.
File this one away for the end of year if you don't use it now!
