Subject: Re: [baidarka] Gunwale height
At the risk of inspiring incendiary missives, (INCOMMING!!!!) might I ask, if
there are skinning materials such as nylon out there,(which I found to be
fairly easy to work with), what are the properties and advantages of choosing
#10 canvas? Or are there better skinning materials than the two mentioned?
Or is this part of the great Vanilla/Chocolate debate?
