Shannon, The sturgeon skin will be great for this bow. I will send you, or who ever, the rattan for the handle. How wide are the skins and how wide is the bow? Can you split a skin lengthwise so you can use only 2 skins?
  I never worked guava before either. I believe Manny would heat treat the bellies of his bows.    I would think that 65" would be long enough for a 28" draw. 
   Dane, That would be a wonderful jesture of North/South cooperation. A woven bow sock would be a heck of a lot better than Greg's tater sack...even with the writing showing. You will forever be in our debt...and out of our picket sites.      Pat
