Is there a local shop that can help? I do some charity work for. We meet and do all of our stuff for the most part at a local shop, we have part of one of the class rooms there where we keep all of the supplies etc, they even loan us machines to use that some of their classes use.
There are other groups here as well in town that when we get donations that we can't use we donate to them, And maybe through the store can also get more volunteers to help put together some of the quilts, using up more of the supplies.
