The beautiful thing about charity quilting is that it is very individualistic. I could spend 200 hours and $200 on a charity quilt and make only 2 per year. Or I can take a simple design and decent fabrics from my stash, donations, or garage sales and make several per month.
In either case I want to make them attractive and lasting. I do not use loose weave fabric, and for children's quilts, I use 1/2 inch seams with small stitches.
I am a former coordinator for Project Linus, the biggest "downer" of the job for me was handling (and sometimes mending) the bad blankets when they came in. There weren't many, but the few that we had were demoralizing -- quilts made from old faded curtains, fabric with stains and holes, open seams, etc. Most recipients don't notice or care if the points are cut off on stars in piecing, but they do notice if the quilt comes out of the washing machine in rags.
