I saw this idea on pinterest, of course! When I saw the idea I knew I had to do it right away. Mainly because my drawer was getting full of lovely cards and letters from friends and family and I've always wanted a better way to store them! They are treasures to me!
I found these small binder rings at JoAnn's. I used a %40 coupon and got 2 for $2!
I have one organized with cards from past photography clients of mine. It ranges from graduation, wedding, and birth announcements.
