I would probably fix the blanket or whatever and return it to her in person so I could have a conversation with her. I would just explain that while I do know how to make all of those types of repairs that she has been sending to me, I actually am a quilter and I focus my time in that direction. Give her the sewing kit and offer to teach her some tips on sewing and also offer the name of a business that does sewing so she has some other alternatives. Being young and being away from home is so difficult for some Military spouses. Not only do they need friends and companionship when their spouse is away but it is also hard for them to know where to turn when they need help. It will take her a while to learn the ropes and to know how to get up the gumption to go out in each new place to find the services she needs. I know my own young daughter struggles with these things as a Navy wife sometimes. She is getting better with my guidance but it has taken three years of talking and teaching her how to get things done. She has learned to network with other women as well to garner information from them. Perhaps this is all this young woman needs. Personally I'm a little put off by your comment that you don't want her as a friend. Being helpful doesn't mean you have to be chummy and go out for lunch and shopping after all. Besides do you really have more friends than you can stand? It's quite possible that this young woman never learned manners or how to survive from her own family, I say she just needs some guidance and I would give it to her while standing my ground.
