I found some great free templates for mini wallet cards at The Album Cafe. You must have photoshop to use them and instructions on how to use the templates were provided. I needed them! I spend too much time fumbling my way around photoshop elements but I am finally starting to learn.
I put 2 pictures on a 4x6 print. Making these personalized valentine cards were just as cost effective as buying the box of cards from the store - I actually think it was cheaper. I spent $5.20 and ended up with 58 wallet sized cards. Enough for both school classes and a few extras for family.
These cards are unique and a perfect size for the classroom valentine exchange.
