Both of my grandmothers were quilters so I suppose you could say it's in my blood! I've always been an artsy/crafty kind of person and I tend to jump from hobby to hobby and I've only "seriously" been quilting a couple of years, but I made my first quilt when I was about 7 or 8 (with help from Gran, of course) and made a few other baby quilts randomly through the years.
I love the design aspect of it, and I love fabrics and colors, so it's a bit natural. And as someone else said, this is something I can make and give away and not feel like I'm just giving someone clutter.
I also feel like I'm helping keep my heritage alive. My parents and their siblings and also my sister seem to have missed the "creative" bug that has bitten me...aside from my grandmother's creations I grew up in a world of store-bought, pre-made everything. Soup came from a can, clothes came from a store, if something frayed you tossed it out. Then I'd spend time with my grandma and witness the magic of soup being created from scratch, clothes being made from scratch, and all sorts of things being made out of what I would have considered trash otherwise. So, I've taught myself how to cook, how to sew, how to make a lot of household things (soap, cleansers, bath mats, curtains...) and am a huge fan of the idea of "upcycling". I am young-ish (still in my 30's) and work full time so I do still buy a lot of pre-made things (clothes, for example...I still don't know how to make my own clothes) but some day I'll get around to learning how to do that, too.
And the neat part...I don't have kids but I DO have a niece and a nephew...I am glad that they are exposed to things made by hand. Maybe they will pick up some of these things some day too, maybe not, but the exposure certainly can't hurt. Meanwhile, when they visit they get to pick out a cozy quilt, their own bar of handmade soap to take home, and help make and eat food that (as my niece says) "is made from INGREDIENTS". That gives me some serious warm fuzzies.
(Not that I am criticizing how my sis is raising the kids...she's a single mom on a VERY tight budget and does a great job with her kids in all the ways that really matter. She works her butt off and is an A+ mom in my opinion - I'm super proud of her.)
