I also cased this off one of my friends secret sisters projects. It was pretty simple, the basis is 3 regular letter envelopes sealed & cut at 6 7 & 8 inches, bound together so they flip, some coordinating paper and some embellishments, I haven't completely finished embellishing the outside or the inside front envelope. But I won't do that untill I give it to someone and I usually don't remember to take a picture before I give it away! LOL. If you require exact measurements just let me know.
