Besides printing them to use stand alone (as a card or page etc.) try using them in collage work. Or if you print them on a laser printer they can be used with hot foil and a laminator or foiling machine. Laser prints can be transferred using acrylic mediums and are fun to use with a gelli plate (see this post here  and this tweak here ). If you have ink aid or other printing media to allow painted surfaces to go through your printer, it is really fun to print onto different mediums, materials and substrates like I did using InkAid here!

What have you done with a digital print?
