Has anyone done any glass etching? I really want to try this out but I am waiting until next week when I can buy the etching cream for 40% off since it's 30 bucks for the bottle at Micheal's :? Anyways just curious if anyone has tried this? I have read several tutorials and it seems really really easy. I want to etch names into 9x13 glass pans for mother's day gifts. As well as for 2 SIL who have birthday's in May. Any tips or suggestions! thanks :)
