My other addiction: ukulele.
Bought an inexpensive ($40) Makala ukulele, sanded the finish off and painted the image that was in my mind's eye when I looked at it...Thin layers of acrylic paint, a shellac finish and it still sounds decent..Still want to have a cleaner finish, no brush marks, no blobs, but need to take the strings off and spend some time sanding and polishing...Right now I am having too much fun playing it..
Got great advice from Mike Da Silva, uke builder extraordinaire! http://www.ukemaker.com/
All I need is the patience.
