I created an envelope box the other day that would be the perfect size for treats. I decided that I wanted to change the size just a little so that I could create a box for 3x3 note cards and the some mini square envelopes. TADA!!!!
It still has the same basic design - an envelope appearance, but just more space. The finished box is 3-1/4" x 3-1/4" and 3/4" deep. I also had a little fun by adding a faux button to the front! TOO FUN!
