Guardian, I am going to try and make my own decals with this decal medium.
http://www.beldecal.com/inkjet_decals.cfm I am going to buy the white backed paper. I plan to use my scanner to scan in plastic model decal sheets. Then I will put them in Adobe Photo Shop to enlarge them. Then I plan to print them on my Epson 750 Photo Stylus inkjet printer. My printer will print an 8x10 color glossy at near photo quality, its very sharp so its should make good decals.
Good Luck Viper
