I found a book at goodwill the other day when looking for books to sacrifice for an invisible bookshelfthat is really freaking awesome. I picked it up because it was the exact kind of book I was looking for for the project, but then I realized what it was and I might have peed my pants a little bit from excitement. It was Reader's Digest's ABCs Of Nature! How neat! There was no way I could ruin this book for the project, but I still bought it for my own enjoyment.
It has so much information in it, and it has such nice illustrations in it! This is definitely one of the best things I've come across in a thrift store, and it was completely by accident!
