Here's a card I made for a GF daughter who just received her Master's from Florida. I wanted to try the box card...
I think it is a fun card and will definitely give this type of card another try.
Here's the Details:
Image - clip art I found online; I added the graduation cap.
Sentiment - both are from Stampin' Up: Starburst Sayings & Occasions Alphabet
Papers - all from my scrap basket
Extras - Stampin' Up Starburst Framelits Dies, tag punch, rhinestones, brad, CM corner rounder & ribbon
Here is a tutorial for this type of card: Card in a Box I did adjust my measurements so my card would fit in a 5x7 envelope.
Hope you are having a crafty day!
