Ya want the low cost, low bulk quickie method?
Paint them on...or silk screen, but that's a pain.
Yeah - I'm serious...make a poster board template with several in a row, measure and mark the field then use a laser level for alignment...goes fast, especially the 'back' side - keep a single star template and touch up when needed.
Two hours vs. two weeks!
Sounds good! What kind of paint do you use?
