As a subscriber, I have been able to call on John Cavender at Boat Canvas University for technical questions from “best size for my next cutting table”, to, “which way should the Kedder welt lay, on the radio arch of a SeaRay when I pattern the aft enclosure” [If you have a hard time envisioning the elements of that question, then you might gather how valuable a thoughtful and definitive answer was!] I have 40 years as a self-employeed professional upholsterer with 2 years on boat enclosures. I wish I had met John 2 decades ago! I am looking forward to a workshop at Boat Canvas University. As a second generation boat canvas professional, John brings a wealth of knowledge to his enterprise… AND SHARES IT generously!
