I'm looking for tips on making prismacolor pencils adhere to
Hi, you mentioned using sandpaper and steel wool, sounds like you
need a much rougher grit of sandpaper. You need 180 or so to
approximate the effect of sandblasting.
There is also a small, inflatable sandblasting booth you can buy! I
have the link on my blog, or maybe you could find it on a google
search. Don’t know if that would work in this application. It’s sold
for sandblasting glass, I think.
