Feline Fanatic, the Vortex quilt is something I've considered. I know a lady in some foreign land under the name "Leu??????" sells her patterns of this sort. Have one on my "Bucket List" so maybe now is the time to try it. Wonder how well they'd be able to sleep under a quilt made up in a vortex pattern???????? Might make them dizzy??????
Thanks Feline.
