Thanks. Yes I have taught myself to play a few chord progressions on the ukulele and the same ones on my daughters guitar. It is definitely easier on the uke. The back of my ukulele is similar to a lute in that it has the leaf shaped parts that make the back curved, but is also has a rim like on a ukulele. I havent really followed any rules. I just made it up as I went along. I use normal wood glue , but it is also possible to use bone glue or hideglue, I am not sure whether it is easier or harder than woodglue, but woodglue is easier to come by.
