Because a quilt is for charity should not mean that it should not be of sufficient quality that one is embarrassed to put a label on it. I'm not saying, buying or making it out of the "best" fabric that you have but it still should meet a certain standard as should the piecing & quilting. The recipients are there for "whatever" reason that life has given them & we should strive to NOT make them feel any less inferior. IMHO
That quilt could be the very thing that finally makes them feel that someone "cares".
