i bought the siliconized batting from joann's on line 20 yardsx 60 wide ,$34.99 less than $2 a yard. it quilts up nicely! haven't had any experience sleeping under it. it lies flat for runners and placemats, and mugrugs! and it has a very drape-able hand. they have a 30 day return policy but i haven't wanted to return it. in an heirloom quilt i'd probably use wool. but for more utilitarian, this stuff seems to be great. has anyone else here tried it?
