I use the thin tissue paper that comes sandwiched between acitate pads (for art and drafting use) It's thin like the stuff the comes with a new pair of shoes. My logo is on computer. I tape the tissue paper to a sheet of paper (taped on four sides) and run it through my laser printer. I also flop the artwork (upside down) so it's on the underside of the tissue when I adhear it. I lightly coat the surface of wood or glass and pat the logo into place and coat over it. I sand that area very lightly and do another coat of epoxy.

Also I cut the logo out fairly close to the artwork with rounded shapes to further hide any paper thickness. It always wets out transparent.
