First, find a book you don't mind ripping apart. I have to admit that I felt a bit naughty tearing up a book, even if it was one that I bought at a garage sale. I intended to read it, but couldn't seem to get into it. So, it has sat on a bookshelf for a couple of years just waiting. I'm so glad it is being used now, even if it's not for literary purposes.
Make lots of paper butterflies.
