I don't know about Knoxville, but in Maryville there is a shop called "Bowhunter's Pro Shop". I know that he can make you a string if he doesn't have one that will fit it. I haven't done much business with them yet, but they seem like good guys.
I had him make a string for a little bear recurve bow I had for $25.
If I remember the string should be 4 inches shorter than the overall length of the bow.
EXAMPLE::: if you put a tape measure on the limb tip & measure it straight acoss to the other tip and its (just say) 55 inches, the string should be 51 inches.
But DO NOT !!! put a fast flite string on that bow, it'll shatter the limb tips....ask me how I know this.
