I have updated the notes to be more clear. In general most all quilts have 3 layers. On most rag quilts we make we use either cotton, flannel, or minky as the top and bottom materials. This quilt has a flannel heart fabric and a brown minky. It seems that I did not include a picture of the back I believe it was all flannel. Our center layer we mostly do a cotton batting. The batting layer is cut 1 inch smaller then the top and bottom so when sewn together it is not part of the frayed edge. We have at times though added a flannel or cotton fabric middle that we cut the same size as the top and bottom square so that the color would show in the rag part (normally a off color) to add spunk to the design. I hope that answers your questions. Feel free to ask as many as you like as I love to try to help other quilters.
