Here's a card I made recently for my cousin's high school graduation. Blue and gold are the school colors (but yellow is always substituted...I'm also an alumni from the same high school). I had difficulty finding graduation paper at my local craft stores so I made my own (personalized) paper at home. I got inspiration or this card off of the Cricut MB (thank you!).
I would have liked to make the cap blue or some color to stand out but the high school graduates in white caps & gowns (and I wanted to stay true to that so it's a bit more personalized)
(the little pocket is for a monetary gift)
