It is a perfect size in my opinion! you will love it! Just take your time (i did). There is also a pic tutorial on this site... It helped out a ton when i questioned myself! It was so much fun making it and learning new things!
It wasnt as hard as you might think.. to me anyway. Map it out and have fun! I had never made a "box cut" before until this and i was so tickled when i did it! The fact that you can adjust/modify the pattern to the way that suits you best is what is so cool about this!
I got my pattern from ebay... You can find good prices there if you cant find the patter at a LQS!
Good luck! i cant wait to see yalls bow tucks!!! and thank you!
