As a sailmaker said, "it takes a real man to sew boat gear. The sewing is easy but cutting your own hand free and then cursing for 30 mins without repeating yourself after you sew your hand to a sail, takes a real man". I saw that once, I can confirm the cursing part but, I had to cut his hand free. I sucks to sew your hand to a sail, with your shears just out of reach.
Call me twisted but that last sentence made me laugh.
