NOTE: This was one of the first things that I made using my new toy - my new laminator!!! (My husband said that I am becoming obsessed with laminating - HA!!!)
I made all my pages in Photoshop. I put the letter and then put an object that starts with that letter. (For Example: A is for Apple with a picture of an apple). I then put on the page how to build the letter. I used foam sheets to make my letter pieces.
I laminated the pages and then bound them with metal shower clips (I can't seem to be able to find craft rings anywhere right now!!)
I got a zippered pouch to put the letter pieces in (I found binder pouches at Wal-Mart for $0.97) and attached them to the book through the rings.
Aaron is still a bit young to grasp how to do this yet...but Seth sure had fun helping show him how to do it. I think this will really be a handy tool once Aaron is able to grasp it (and it then can be used again for Alyssa)
I am also wanting to do a book for lowercase letters and for numbers.
