As I was trying to figure out what material to print on, I came across static cling...and let me tell you, Static cling by far is the best material to use if you don't want any residue at all. It might sound like it won't stick well but trust me when I say that I used it and it worked perfectly. No residue and it didn't come off at all unless you peeled it off yourself. You could buy 25 packs for inkjets and it only costs around $20 or so (and think of all the designs you could make with that many sheets!). I was going to start selling my own but with the weak reinforcement from my boss, I just can't get the ball rolling, so I'll be submitting my work to some of the companies that are already selling some and collecting percentages. All you would need to make your own would be a sheet of static cling, an exacto blade, and a creative mind. I'll post some home made ones in a week or so (waiting on paper delivery).
