I used to sew Christmas gifts for all my nieces. One year, one SIL asked me to make a party dress for her daughter. I made a coppery silk shantung into a beautiful party dress, if I say so myself. I had to call my BIL at work and ask if the gift had arrived (I sent it Fed Ex) because I didn't KNOW if it had arrived, much less get a thank you call or note. I got a huffy call from that SIL the next day, complaining that I'd made her look bad. I told her I'd tried to call the house and nobody answered, that I had spent a certain amount of money on shipping the dress, let alone my time and effort on materials, and I wanted to know if it had arrived... And no, I never sewed for that neice again, even though it was not at all her fault that the gift went unacknowledged - she was less than 5 years old. I would have been fine with a simple phone call telling me it had arrived, and thank you, and I was offended that I got nothing.
I've been given fabric when my MIL died (all coat weight wool) which went in storage for a few years, and is now being used by my youngest, who just completed a dress design program. I also got fabric when my own mother went into assisted living - much nicer and lighter fabric, but still not my style. Went in storage with MIL's fabric, and DD#3 is poking her way through it, and will donate it to school for their use, if she decides she herself cannot use it. Anything else given to me is taken and set aside until I feel like sorting through it. I never promise to use anything of it, and I only rarely sew on request anymore. That may well change once I start getting grandchildren.
Mending - only for close family, nobody else. A friend gave me dirty things to mend once, and I mended them, but the next time she asked I told her I was too busy, sorry. Family gets told that either they take it back and launder it or I will, and next time do NOT give me dirty things to touch!
