I hope you find a way to reach these people without creating hard feelings, because this situation needs to be addressed in my opinion. Charity quilts or not, these seem to be sub standard, and the recipients deserve better. I was not clear as to whether the fabrics are washed before you work with them, but it is risky for you to handle them if they are not. We are getting warnings right and left about stored fabrics and old clothing being a nesting place for bed bugs and other insects, not to mention mold. I'm afraid i would have to bow out and donate my time to charity in a better way. Good luck to you if you decide to speak up. Maybe you will be surprised and find that someone else in the group will stand up and agree with you.
