Ditto to the others ... have never heard of such, and hope you will share us more details as to how it all happens, once you know, too.
Another idea ... of course, depends on the quilt design you have chosen ... roll or fold the quilt and tie with a ribbon. Then attach a single block from the quilt done as a mini quilt that could be used as a mug rug, vase mat or whatever. That way you know your quilt will be "cared for" til it gets home, and everyone at the shower can get a peek of it with the single block quilt.
