You're right, you shouldn't be ashamed of the fabric that's being used. It's a charity quilt, but someone is going to be using it to warm themselves....stained or faded fabric, well there's just no excuse for that. I also belong to a quilt ministry. We started the group 6 years ago by asking for donated fabrics and the church gave the ministry a minimal yearly amount of money - $300 for batting and backing. We made the decision early on that we would buy muslin for the backing as we didn't want to waste what good fabric we had for the backing. When the boxes and bags started showing up at church....we went through them setting aside non-quilting fabric (upholstery, corduroy.....) to give to another ministry called "Bits and Pieces" in our area. It became quite evident that when a person decided that the bag of fabric was going to be donated....no one looked inside. We actually took one bag directly to the garbage as it had mold throughout. My thought on charity quilts is that you should be proud of what you made at the end of the day, knowing that you would be contributing to someone's self-worth when they received it. When we ran out of money for the ministry, we decided each month to host a pot-luck supper between us.....one person would cook and the rest would contribute $10 towards the ministry. I don't know how you're going to change the people's minds at your church, it's a shame that thrifty has become miserly.
