I began by cutting a backing for the money. Started out with cardboard but switched to black cardstock for a better look. The front cover was cut to the same size in red.
I asked the bank for new bills, but they were only able to provide the best they had. So I ironed them with great results.
I punched out red 1" circles for my Lego bumps
Used pop dots to make them stand proud.
I downloaded the Lego logo and glued it to the book to save time.
After carefully aligning the edges, I clamped them with binder clamps and painted the left edge with Elmer's Rubber Cement. I let it dry for a couple of hours.
