90" x 36", $21.99. Yes, pretty expensive.
The instructions state not to wash the backing fabric. This would be a deal breaker for me.
I'd wait for reviews on this batting.

$21.99 a yard with 3-5% shrinkage, I think not. If one needs to order directly from the company, possibly no discount coupons or sales. No prewash, not enough incentive for me. Just bought some 100% cotton batting, a first for me, not sure I like it. Instructions are to soak in hot water for 20 mins, wring and dry flat. This could take all day.

Millymccoy, I don’t understand how this batting allowed you to not sandwich on the floor. Am I missing something? What is different?

Reminds me of the story boards my mom made for us kids when we were little. Cut out paper dolls, drew furniture or cut out pictures from magazines, glued felt on the back. Had a huge chunk of cardboard covered with flannel. The dolls and furniture stuck to the flannel, and we played dollhouse for hours and hours. 😊

I have never heard of that kind of batting.

Thinking about using it
 

It is about twice as much as regular batting, but if it would help me not have to crawl around on the floor on my 71-year-old knees, it might be worth it. I noticed the by the yard is cheaper than getting a twin size. Might save a bit that way.
