My friends and relatives know how to sew and I'm not asked by them. Hubby and my son, do ask. My son knows how to sew, I taught him many years ago. He doesn't live close, so doesn't ask often. My response is always the same, though. I'll look at it and see if I can do it. If not, it's up to the guys to decide what they want to do.
At one time, I worked at a high school. They knew I could sew and they pretended to be too strapped for cash for new athletic uniforms. They wanted to know if I could fix them. I said I'd look at them and see what I could do. I thought I could fix some of them, but warned that they might not last more than one or two seasons. I also said I charged for my services. I told them it was $20/hour. I got the job. They didn't pay me that much to do my regular job, but they would for repairing uniforms? Amazing.
