i got so busy pontificating, i forgot to suggest a solution to 1rottendog.
if you haven't already done so, prepare an information sheet for prospective donors that outlines the requirements and expectations.
when you receive quilts that are too poorly constructed to be of use, you should reject them and return them to the donor.
however, that should be done with as much kindness as possible.
it could be that the quilter is not aware of the problems; what causes them; how to fix them; or how to prevent them.
instead of saying, "we don't want this", say, "this will make a wonderful addition to our collection if you will be so kind as to fix ..." whatever needs fixing. if that person lacks the skills, the request should include an offer for personal help from an experienced member of your group.
99% of the time you can turn something negative into a long-term positive for everybody involved.
