I use thin batting if I use it. I cut the batting smaller then the squares of fabric so it won't show in the rags. Before I got the rag die I used spring opening scissors to snip. Heritage brand are the best rag snip scissors. Its so easy with the Accuquilt rag die. I sandwich the fabric, quilt as I want or make an X in the layers. I then cut the snips using the machine one block at a time. . I sew blocks together leaving about 1/4 inch from the solid to the snips. For fluffy rags homespun is best. If using flannel or fabric for batting I cut the same size as the block fabric so it will be part of the snips. I make a lot for donations quilts for older kids/teens.
