I'm just going to throw this out there.........
In our sleepy little New England town, they have arts and crafts day for the kids at the local library.
Honestly, you've got my wheels turning on this. Maybe I could take one of my old acoustics and let the kids "have at it." Do it in water-based paint, or acrylic or something, so if I don't like it, you could remove it with Goo-Be-Gone or something.
I bet it would end up looking pretty cool. Also bet the kids would love it.
AND.....
Then, you see......the MILFs/Soccer Moms that run the arts/crafts day at the local library would swoon and ask you about your guitar playing.
Next thing you know, you're doing the local arts/crafts scene and banging some hot soccer mom across town.......I mean, you KNOW they put out.......
Wait, that might be too much......but I bet your guitar would be cool looking.
Never know, might get you a paying gig.
Would be a cool thing for everyone involved, though.
