Cards for soldiers

I recently was in a stampin up club and every month the host sent us a card kit. This is one of them that gave me inspiration for some easy cards. I did 30 of these they all are being donated to cards for soldiers. 

The example:

The 30 I came up with. All were made using scraps that I had. For these you need 2.75" squares and 8 1.25"squares.
