For the ladies in our families, I made etched casserole dishes.
I designed individualized templates with my silhouette SD and let my machine cut them out of contact paper. I then peeled off the template, placed it on the glass, and brushed on etching cream in all the negative spaces.
The directions say to leave it on for 5 minutes, but I learned quickly that 5 minutes wasn't enough---and actually had to re-lay two of the templates ( that's hard to do on a long last name!) and re-etch. Pain in the ass. So, to save yourself the frustration, lay the cream on heavily, and wait 10 minutes before rinsing off the cream. It made a world of difference.
