Hi Harold,
Making your own decals isn't hard. I don't use the Archer paper; I used Testors clear film paper this time' but have used others as well. It is pretty much the same though. As I said, I design the decals in PowerPoint. Then I print a test page on regular paper to confirm size, font, etc. I then cut a piece of decal paper slightly larger than the area of decals I want to print. I use scotch clear tape to tape the piece of decal paper over the area I want to print on the test paper; seal all edges so the print head doesn't catch the decal paper edge. I then run the piece of paper through my inkjet printer (make sure the paper is compatible for your printer - they make inkjet and laserjet paper). Once the decal paper is printed, let the ink fully dry for about an hour. Once dry, spray the decal paper with clear topcoat (gloss or flat) to seal them; let this fully dry for an hour or two. Once dry, carfully cut the scotch tape to release the decal paper from the larger sheet. Then cut out each decal and apply like any other water-transfer decal. Good luck.
