You may want to distribute the information to any local thrift stores also. Unfortunately these things often end up there and they can keep an eye out for it. Often these people that rob homes just grab something to bundle up or cover the items they carry out and wouldn't have any interest in the quilt itself.
It disguises them so the neighbors won't get suspicious. Sorry this happened to you. I have a quilt that has fabric in it from my deceased DIL and would be heart broken if something happened to it. It is ear marked for her daughter when she gets old enough to appreciate it. Ann in TN
