Golly! That purty striped wood shore is enticin', ain't it! It could definitely make an impressive rifle, but...Have you considered getting another 'plain' piece of wood to start with, and putting that one on a shelf for the next gun? I know it adds up $-wise, but I think fancy wood is intimidating, 'specially for newbs like me! I have a hard time using nicely figured wood in the wood stove when I cut it myself, and tremble at the thought of burning up wood I paid for. Think of the last horn you made...could that have been your first horn?
Like others have said, that partially cut wood can limit the style a little, especially if you're not sure what you want out of it. Books, and lots of pics, and handling some other guns will help a lot.
I bought a parts set with some amazing wood, and knew almost right away that I wasn't up to the task. I also knew if I did screw it up, I'd have a hard time forgiving myself, and might not build 'the next one'. So I put the purty-wood gun on the shelf, and bought parts for 'the next one'. Plain-er style, plain-ish wood, and a style gun that I knew I would be wanting down the line anyway. I can mess this one up a little, and get in some much-needed practice with tools and techniques. I know as long as it shoots like I want it to, I'll be happy. It's a hunting gun, so it'll get broken-in, by my hand, and that will make me even happier with it. YMMV!
