I have started to use no pill fleece - a good brand which I get when I have coupons. As I do all my own FMQ on my domestic machine, it works so much better using the fleece as batting isn't needed and the fleece stays put when it is pin basted. My grandkids all like soft backs and this works so well. Sometimes regular backings with batting and then quilted can be kind of stiff.
It is especially good for little kids and baby quilts.
