So, I (with the help of my sister in law) raided my cabinets and dug up some of my Pyrex glass dishes. I think we did about 6 pieces and then the next day I did 6 more things on my own. The label warns that not all pryex will work. We only had one dud out of about 13 pieces.
We used vinyl letters that were in my scrap booking kit. I know I've had these letters for years. I'm not sure what options are at the stores now, but I would guess there are more choices. Then, painters tape was used for the edges.
After washing it off and drying the dish, the etching appears. These pictures do not do them justice. They turned out really cool. I used out last name on a few pieces (my crock pot lid, a 9 x 13- things I often take places). On some other pieces, I used words like delish, yum, food, grub, leftovers, treats, so good, etc.
I have my eyes on a mirror and a vase in the living room, but I think a different font would look better. I'll have to keep my eyes out at the craft shop.
