Linus Project, Downey Quilts for Kids, Quilts of Valor, just to name a few legit charities that need quilts! Others here will have more. Also, nursing homes, cancer units, etc.
Enjoy your gift!
Sorry, just reread your post, unfinished tops can be done by many LAQers who do this for these organizations. If you contact the organizations they will surely have a list of quilters who may help you finish those tops.
