Sorry for the crappy pictures. :O( I forgot to take my camera when I gave it to my mom so this is as good as it gets. The top of the wine glass is etched with her initials, the bottom says "One's my Limit" on both sides of the circular bottom. The wine glass itself is about 2 feet tall.
I used the KNK to cut a stencil from white Oracal 651, the outdoor vinyl. I then used Armour Etch and it works like a charm. I bought a small 3 oz jar and that will last me forever. You apply the cream to the area you are etching, wait 60 seconds, scrape off the excess Armour etch and put it back into the container, rinse with water and it is done. Because you can reuse the salvage it lasts through many projects.
