Not to worry, I had another project waiting to be finished for them as well.
If you have not tried etching yet, let me tell you that the reveal is well worth it! I left the creme on 20 minutes for the goblets and 30 minutes for the plate, The etching was fairly even and consistent. I think this was due to my generous use of the creme (which I did salvage and place back in the jar).
You can also use an air eraser to etch as well. I have the supplies for this but have not had the time to set it up yet. Oh well, Linda's brother is getting married in August......I am sure I will have more projects, lol!
Added later: This stuff is addicting! I made up 6 dinner glasses to go with the goblets. Straight-sided (not convex) glasses are so much easier!
