Please enjoy the process of deciding what to do with your inventory and don't let it bog you down! Seems like the attic is holding your things just fine! I do want to correct the impression that Project Linus quilts are not serving the local population. My guild does a wonderful job with Project Linus and, by a huge percentage, the bulk of these quilts go to local kids. When I had to have PT, my therapist was raving about how much her son still loved the PL quilt he got when he was hospitalized at 4. Also, I don't have to do anything but piece tops for PL as others in my guild enjoy taking care of the other steps in quilt construction. We also take fabric donations which are then made up into simple kits as some like to work from precuts.
Just let the right organization(s) find you!
