Above is some pages from two felt books I have been working on. For the longest time I could not find anything sharp enough to cut felt, finally I found a old pair of scissors that did the trick.
I wanted the felt books that I made to be easy to play with and can go on road trips with us.
These are no sew felt books, I used hot glue witch in my opinion I think looks and works way better.
Depending on age try to add some things like counting, abc's, colors, and shapes.
