Envelope Book - cats

This is an envelope book I made for my friend Sally who is a cat lover. She has three of her own, the cutest funniest little tuxedo cats you can find. And she volunteers at a Cat Shelter every week. I've been thinking about doing a cat book for her for some time, and one day as I was thinking about recycling junk mail envelopes, I decided to construct a book for her birthday. Here are the pics.
