Cut your batting and back about 1/2" larger than the front. Lay out as in picture and sew 1/2" around leaving an opening to turn the right side out. Trim close after sewing and before you turn it.
Now you are almost done. After you turn to the right side you need to close the open end. I sewed around mine with 2 rows of stitches. To finish stitch in the ditch. All done. I made this set of four and gave it to my sister-in-law. (she loved it) Feel free to copy and paste and make your own set with fabric you love.
