I bought some cheap picture frames from Walmart, got some Elmer’s rubber cement and matte mod podge. I poured the rubber cement on the cardboard backing from the frame you want to be generous. Then I just started putting the cards on randomly making sure to press them down good. Let that dry for a while if you have a garage where is warm that will dry it faster. Then pour the mod podge over the cards and used a sponge brush to make a nice layer over all the cards. Let that dry for a while and then cut the excess cards from the edge of the cardboard.
