I have been making microwave bowl cozies for quite a while now and have decided to remake them into different sizes. Today’s size is 15×10 inches. 
In case you would like to make one for yourself or for gifts.
I started with cutting an oval that was 16×11 inches out of 2 pieces of fabric. One for the inside and one for the outside. Then 2 pieces of cotton batting. I then stitched one piece of fabric and one piece of batting together. I did this for both fabrics. (Sorry for the shaky green lines)
Stitch darts the middle of the top, bottom, each sides.
I started at 3/4 inch from the corner of the dart and sew down 4.5 inches. Do this for all 4 darts, on both pieces of fabric/batting, pieces.
Place them together right sides facing each other and stitch around leaving an opening for turning right side out.
Trim and turn right side out and then stitch closed and it is ready to go.
Enjoy. Any questions just holler.
