I purchased a bunch of shadow box frames several years ago from Target for $3.24. (Does anyone ever buy stuff at Target that isn't on clearance?!)
This project was very easy to make. I traced the "E" and cut it out, added some bling, and that's it.
I am always amazed when I see all the things that can be made out of paper!
Speaking of Target, what is the best thing you have ever found at Target on clearance? I have found too many things to count! I think the most useful things have been hurricane-supply items. A few years ago, when south Florida (where I live) was hit with two major hurricanes, we were so happy to have that metal contraption that lets you make toast on the grill! :)
