What to do With Flashcards

A generous soul gave me a box of flashcards. There are about 200 of them. They are ivory card stock, about 8.5 inches long and 3.5 inches wide. Sturdy with rounded corners. Each one has a word on one side, and a small number in the upper left-hand corner.

The other side is blank.

What do I do with them?
I’m looking for creative, interesting ideas–not ones that anyone might think of–bookmarks, journal covers, journal pages.
If you give a suggestion, please make sure you include some sort of directions, so I can understand what the idea is.

And if I find an idea and love it, I’ll share some with you–let’s say a dozen.

Leave your suggestions in the comments box.
