My dear friend got married last month. They didn't have a registry, and didn't really need anything. Hooray! I good excuse to make something instead. I much prefer personal gifts, anyway.
I saw this idea online and thought I'd try it for their gift. Sorry I don't know where I saw it, but there are several resources for etching glass if you google it.
The first thing I did (after I bought a $7 casserole dish at Wally World), was sketch a bunch of ideas to decide what to put on the thing.
Then, I cut everything out and taped it on the dish to get the right placement.
I put the tape all over it, to make it a big sticky sheet that would keep my design all in the right place. Then, I peeled it off and stuck it to the top of some Contact paper.
I took my Xacto knife and cut the design out.
Next, I peeled the backing off of the Contact paper and stuck it on the dish.
Then, I took the etching cream and just smeared it all over the sucker.
I let it sit for about 10 minutes, rinsed it, peeled the Contact paper off, and Viola!
