I made some little cards for my daughter's friends.
I made an A2 card that has a fold on the 5 1/2'' side, then cut it in half through the fold, so the dimensions are 2 3/4 x 2 1/8''. There's just enough room for a little message inside. I attached a tag onto the front, and put into a glassine bag. Quick and cute. I wanted to put some treats inside with it, but still too much of a choking hazard at this age.
