I printed on fabric. The fabric sheets were too expensive for 50 pictures. I used bubble jet set (on Amazon) and followed the directions. Then I ironed the "processed" fabric to freezer paper (shiny side of freezer paper goes down on top of the fabric) then taped paper on top of that.
Here is a link to how I found out how to do it.

Hope this helps!
Nice thing to do for your son. I dried my sheets on my folding clothes dryer since I had so many!
