- Firmly press the edges of the resist you are using.
While contact paper is a lot cheaper than vinyl, it does not hold as well and when just a bit of that etching cream gets under the contact paper it creates a messy edge.
- Liberally - and I mean liberally - apply the etching cream. It can have a tendency to go on thin. But you've REALLY got to get a ton of the etching cream on the glass.
- Leave it on - FOREVER.
This last time, I was going to leave it on for about an hour. Then I forgot about it and it was on for about 4. And I finally got the results that I wanted. So from now on, I'll leave it on overnight if I have to.
- Go for a smaller etched area.
Trying to "go big" with your etching area, really opens you up for error. Go for a smaller, more subtle effect and you'll actually multiply that impact with a crisp, clean finish.
