Made a couple of tater bags using the warm tater batting but they are so thick compared to ones i have seen at a a quilt show. they used a very thin 100 percent batting. but was curious cuz i thought i had read this on another post - can you use flannel as batting for these??? also i thought i had read where someone used flannel for the insides??? sorry i keep going on about these. i love my tater bags but they just seem sooo thick to try and sew - let alone try quilting on them!
