Best Upcycling Idea Yet!

I had a post about what to do with ruined picture books.  There are many, many more ideas floating around in the e-world... most of them have to do with decorating or some such. But this activity is what I think is my new favorite because it is fun and functional!

What does one do with those board books that get all beat up and the spine falls apart?  Toss 'em?  No! Turn them into lacing cards!  Here is my very quick initial trial. I just need to get a slightly smaller hole punch now for perfection! I could barely take a picture before it was immediately requested for play.  :-D
