Lee, just thinking out loud here but did you consider using a wider piece of biothane for the inside piece instead of leather? I haven't made a pair yet but I have 3/4, 5/8, and 1/2 inch size biothane. I was thinking the whole reason to use biothane was it wouldn't wear out where the leather on the inside would wear out way before the biothane and you would have to replace it probably after a season. I know you fringed it at the top and bottom but my understanding is you don't have to fringe the biothane. Again, just thinking out loud because I have no experience with biothane yet.
