One of the reasons I don't quilt with my church's quilting group is that they make dreadful quilts! Not all of them, but many. The woman in charge says "they can't complain about what they get for free" and doesn't care if the are tied 8-10" apart (the batting will never withstand washing) and with a mixture of cotton, polyblends, and polyester knit in the same quilt! Then they serge the quilt instead of binding it.
I do think that the end use of the quilt matters. The homeless shelter really likes quilts made from polyester knit and with a backing of fleece, but for children or most other charities I use tightly woven 100% cotton fabric because it withstands washing and "loving" better. I can find good fabric at lots of places (though it's easier at some stores than others!). I always use a double-fold binding because it lasts better than others, but everything is machine quilted and the binding attached by machine.
