This site is accepting 12 1/2 inch blocks, which will be made into quilts for people who lost their homes, due to flooding in Tennessee. You can make one or many. It says that the last date is Sept. 1, but I called to see if I could send in some from my guild in mid Sept. and they said that it would be still going on for some time. There is an email address if you want to contact them. This is a chance for us to help others.
