my maternal grandmother and aunt always shop and make things for craft fairs..... my grandmother always got us hat and mitten sets (that i always wore around her... seldomly wore them to school because i have always hated wearing hats and mittens.. i'm a gloves type of person but i sucked it up for her).
when my first son was born my grandmother had someone make some sweater sets (they were girly... we'd thought he was going to be a girl) and i told her thank you and then just left them put away (advantage to living over 300 miles away!). She also had a couple of afghans done for him when she found out he was a boy (she asked about the sweater sets, i told her that i had put them away because who knew, next time it might be a girl!). My aunt made him a quilt (precious moments, i don't care for precious moments but that's besides the point) and a wall hanging (again precious moments) with his birth stats on it... i hung up the wall hanging (next to his cookie monster poster LOL) and used the quilt when we were in the car, at MIL's, etc... he still has it and uses it periodically.
when my second son was born, a bunch of the ladies on the crochet list i belonged to put together a gift box and in it was a set (bonnet, sweater, booties) in red and white. While i didn't overly care for the white I still posted pictures of him wearing it and thanked them profusely because they didn't HAVE to do anything, they WANTED to do it and WANTED to make him something to wear (I still have the set saved with his outfit home from the hospital... it came in handy when we went to MIL's as her house was usually chilly!).
My adopted mom (my best girlfriend really, she informed me i was her daughter, she adopts a few of us and spoils us rotten) made me a gorgous purple velvety Pagan Dress with green and gold trim... i absolutely love it (to the point that as i lose weight, i ask her to take it in for me whenever she says she's just going to make me a new one, i love it THAT MUCH). I also wear (on a daily basis) the two beaded bracelets she made as well as an amber bracelet and 2 amber necklaces that the lady of our tribe made (one necklace was given as a gift, the other my adoptive mom traded an embroidered shirt for at the last gathering because she wanted to give me something nice). This is also the woman that I'm making the socks for (and the lady of the tribe is the one i made the afghan for.. she has also asked me to run an embroidery workshop at the next gathering! I'm wicked nervous!).
I see it as it doesn't matter if I like it or not, they were trying to do something nice for me. Thank them, wear it around them, use it, whatever... then when they're not around I can put it away. They never need to know i'm anything but grateful for their time and effort.
