You know, I've only had one person ask if I took in sewing "from the public", so I do believe that he was willing to pay for it.
I do hem up my own and my husband's pants, and sew my own clothing. I don't do any other alterations, though. But every time I hem up a pair of pants (I'm short-legged, so basically anything not labeled "short" or "petite" is going to be two inches too long, or longer)I feel like I've outsmarted whoever it is that thinks we're all at least 5'6".
