Valentine's craft with one.
Wow, I thought. That saves a lot of paper space to use flash cards. We get just as much on a little card as an 8 x 11 piece of paper it seems, and the little cards are so much easier to store. They are also a little thicker, so using the back is possible after coloring the front with markers.
We'll see how long this lasts =).
Would love to hear your paper overload solutions!
