I've used the "Sunnyscopa Waterslide Decal Paper for INKJET Printer " that you can get on Amazon.

If your edges are rolling up soak it in water longer until the decal unrolls itself.

You are not going to get thick opaque decals like they were silk-screened from an inkjet printer. That said, I am satisfied with this paper. Easy to use. I use a Canon MG5220 inkjet printer and spray Krylon clear lacquer over the decals to seal them.
