This has been a long time in the works. Finished it this afternoon. Backing is fleece that looks like cordoary, no batting. It is plenty heavy enough. Size is approx. 66 X 95. Quilted some of the jars with glow in the dark thread, but was disappointed that it really didn't glow much. This is for my 4 yr. old great-nephew.
Thanks for looking
