I'm the one who ALWAYS gets (and loves), the leftovers. Part of it is I get to use things that are not what I would have picked (due to price or colors or prints), but it gives me a chance to try different things. It also makes me think outside of the box. It also allows me to save my money for special fabrics and patterns or classes. This has also made me learn to work with (and not always run to LQS for the newest or biggest or most expensive items), what I have (just as our mothers and grandmothers before us).
When I'm given fabric it is put into groups - small things - used for crazy quilting, to make bindings, etc... Med things - these can be used to help finish UFO's, making mug rugs, etc... Large things - these go into to groups - LOVE - will use on quilts, bags, etc... DON'T LIKE - if it's Polyester (you know the stuff from the 60's and 70's - it NEVER dies) - I will use it in place of batting (it's warm) - it also makes great stuffing in dog and cat beds too.
Like others on this board I will give to senior centers and kids learning to sew and quilt.
So yes I'm one who is never to proud to take others cast offs, because I can find lots of uses for these items. I never feel obligated, I just always see it as fun and a challenge. And as a quilter I'm always open to a good challenge.
