A really easy pattern to use could be a rag quilt. You can make your blocks 6-8" each. So you would cut your blocks say 8" square, cut a piece of batting 7" square and put the batting between two pieces of fabric, right sides out, centering the batting, stitch an X across the square. Then when you have as many squares to make the size you need, sew them together with a 1/2' seam making sure all the raw edges are on the same side. When all sewn together you clip the edges very close to your stitching about 1/4' or less apart. Fluff it up and throw it in the washer and dryer (cleaning out the lint filter often)

I'm sure that there are others here that can help you better Attached is a picture of a flannel quilt I did similarly
