I made this for @seeuudee in the Felt Badge Swap in June. Both libraries and Harry Potter were listed as themes (among other things), so being the over achiever that I am, I combined the two and created the Restricted Section of the Hogwarts Library.
Admittedly it was quite a large badge, but as seeuudee wanted it more for display than wearing, I thought it would be ok.
I love the addition of the embroidery on the spines. It transforms the rectangles into being recognizable as book spines! The chains are a great touch!
