When I ordered my free prints for that photo calendar, I found myself with 2 extra photos. So I created a 4x6 photo with 2 wallet-sized pictures. I did two of those so I had a wallet-sized photo of each child. I planned on just sending them to a set of grandparents, but then I had another idea. We have TONS of magnets on the fridge. I keep all those advertising ones that come in the mail with intentions of using them for a craft, but I never do.
Well, now I did. I used double-sided tape (a thin layer of glue would be a more permanent solution if you have time to wait for it to dry), stuck the photos on and trimmed them all down. Now, we have wallet-sized photo magnets to send as gifts and they didn't cost a cent.
