you could also do Christmas ornaments. Put in the imprint, and then cut it out, punch a hole in it, and then bake it. And you could give them as gifts, and stuff to family, I'm sure my grandparents and parents would love one. :)
I had to save it. And I will do it for ever kid I have and use them when I design our house.
And you can even add food coloring to it, or just put it on their foot and it'll be a colored imprint and you can do something else with the rest. :)
