you want a light batting try the polyester batting at Joanns ...it is 90' wide and only about $6.00 a yd. I use it all the time...i also use the basting spray to hold the three layers together. It works out real cheap if you can get it with a 50% coupon & and it is quite warm washes like a rag and does not bunch up or shrink. there are different lofts ...make sure you get the least loft...it will also be the cheapest ( if you are not sure which one to get)...good luck on whatever you decide to do.
