I've only used them a couple times, but it's not too hard... Basically, you print your design to the highest quality possible, like printing a photo. Let it dry completely, for a couple days actually is best. Spray it with some sort of sealer... I'm sorry I can't remember what to use... Let that dry for a couple days. Cut it, dunk it, stick it... That's really all there is to it. It does take a little trial and error, but if I can do it, anybody can. I'll try to hunt up what to use as a sealer tonight after I get home.
