Yes. I use a thing batting. I've know people that use up their scraps of batting for them. I haven't done that. My sister makes tons of flannel blocks and uses thin batting for them for all her children and grands, and greats. You can also use regular fabric with batting. I've made one with lots of cotton scraps and they came out great. Also you can make a pattern with them that is made with squares. I've made tote bags with them and they are great.
