I made these way back when with the help of my in-laws and husband! This is a GREAT way to use up fabric scraps. They are pretty self explanatory I think. Cut out letters, stack a letter, then batting, then a letter, stitch, and then trim! It takes some time, but if you can get help it is a project we finished in 1 evening.
I finally pulled them out for my kids to play with! We have been working on learning the alphabet for a while now. Hopefully this helps!
