The letters are all made from the Cricut Birthday Bash cartridge. They are 1 1/2 inches tall. Most of the shapes are various AccuCut dies and Cricut shapes that I had floating around. The felt shapes were glued to the felt (use small dots to adhere if you are going to sew too). To outline the shapes, I used a blanket stitch. The book is bound together with 1 inch binder rings.
The purple one is my favorite because the wings actually flap!
If you decide to make one on your own, expect to spend 2-3 hours on each page. These take a lot of time to put together, but the giftee will love them!
