All great advice. I do agree with Bruce on the reversing. I can reverse my juki at any speed, flawless lock stitches! Anyway not to beat a horse to death...using a sewing machine is a lot like dancing...there's a rhythm and you have to know your partner's limitations! Search YouTube for John Cavco. His videos are great for covers and such!
Bruce, if you wanna unload some tenara, I'm thinking of making some new sunbrella mooring covers as mine have shrunk to a point that getting them on is a hassle (Cobalt not Chris Craft ones)?
