I am also a fan of Warm & Natural or Warm & White 100% cotton batting. But it is a low loft, fairly dense batting. It really depends upon your project, personal preference, your budget and availability. I have used mountain mist polyester batting for fluffy charity quilts too and it is inexpensive. Others love wool or bamboo batting but it is expensive. If you are a "greenie", look at Quilters dream green batting made from recycled water bottles and is wonderful. I also encourage you to compare prices locally and online as I have found some great deals on Amazon and Overstock.com in addition to local stores with coupons. Just try several and you will figure out what you like best!
