Send the wife to Hobby Lobby, Michaels, or other such crafty places. They have plastic stencils for doing crafty things with paint.
Then go to grantcitytools.com and they have the blast resist in different thicknesses.
Clean the stone, or better yet, buy or beg some scrap counter top granite pieces and clean it. Glue down the blast resist. Lay out the crafty stencil and sharpie down the design.
Use a good sharp exacto knife and trim out what you want blasted. Blast. Peel off the blast resist.
Then enjoy the fruits, ahem, rewards, of good husbandry. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif
BTW I got the nicest PM from one of our members telling me he had followed this advice and had great success.
He's now indebted to me and there's only one way to repay.
Pass it on.
