We had great fun today creating our own homemade greeting cards using only, paper, paint and potatoes... Yes, potatoes!  I remember when I was taking one of my education classes in college on teaching arts and crafts in the elementary school, many moons ago, that we made our own stamps with potatoes.  I had not made them since college but for some reason that popped into my mind today to make potato stamps for art class today with the kids and so we did.  (I warn you, this can become addictive.)  We had great fun!  I could go into detail telling you how to do it but if you would just Google "potato stamps" you can watch some pretty detailed video on youtube that will show you in a matter of a few minutes.   Here is one that we watched,  How to Make Potato Stamps  What they don't show you, however, is that you can save your stamps for a few days or so in an airtight container in the refigerator.   Just cover your stamps with water to keep the potatoes from turning black and shriveling up. Potatoes were never so fun!
