You can learn to sail by study and practice, no other way. There are classes, check online and telephone listings. Ask around a marina or yacht club. Read books on basic sailing. There must be video instructions too.
As for sailmaking, there are several good books.The Sailmakers Apprentice by Emiliano Marino is a thorough text. Canoe Sails by Todd Bradshaw is a great book too. Sailrite is a company that sells kits, cloth, and instructions. Look them up. Have fun.
