Sailmaking kits vs. building my own.
I made two sails for my 35'' sharpie ketch from Sailrite kits. I did not learn anything about sail making by sewing them together. I just wanted to make them too since I had also built the boat. As far as the quality of sail cloth, seemed ok to me. I told them how they would mostly be used and they recommended the proper material. They have held up ok. The only problem might be the dacron thread they sent. I used it to also make the covers and after three years the stiching on the top needed to be re-sewn because of UV. If you want to learn sailmaking I think Jeff_H might have the right idea in working for a loft. Seems like you could spend alot of money on sail cloth thru trial and error.
