Won’t Fit

I must be doing something wrong.  I can’t figure out how to get my brand new 2008-2009 Topps Co-Signers Face the Facts insert card to work.  According to the directions, they are suppose to be interchangeable with others cards.  These fall around 1 per pack, and allow you to make your own basketball cards.  Apparently they are only compatible with other Topps Co-Signers cards.  I guess it was a big mistake cutting that Jordan rookie in half 😦

P.S.

I didn’t actually cut a Jordan rookie in two.  It was done with Photoshop.
