I made my sails from a sail rite kit for my 35'' sharpie. Used our old Sears Kenmore model 1240 machine. The new sail cloth is slippery and had to pull it through the machine because the presser foot and feed could not grab hold of it. You basicly tape the seams togther with double stick tape then roll up the material so it is easy to handle and sew it togther with a zig zag stich. The sails turned out pretty good but a professional job would be better I''m sure. The instructions were clear and easy to understand. If I could afford it would probably have it done by a pro.
