Puh, glad you don't give up on this.
Have to give you that point. Found the planing stage boring and just wanted to start. Next time will be very different. It does not only cost time, it costs money. Guess I learned something.I think you just learned that planning is really worth the effort at the start of a project, save your self alot of time.
And I'm doing some planing about the colours for the computer. But I have to read more about etching and try some things before I can be sure how it should be in the end.
