I love the feel and look of polyester but I regret doing more than one quilt using that batting - I live in Houston and usually we only get a few cold cold days (like in the 30s and below) with the exception of this past winter. they are way too hot for down here. :-( I have to leave the heat off and let the townhome get 50 or below to really enjoy sleeping under them!
my faves so far are Warm and Natural or Warm and White...Cream Rose and White Rose(not sure who makes these but got at Hobby Lobby and Joanns), a friend who longams usually puts hobbs 80/20 if I don't supply my own batting. there's another brand we scored discounted last day of festival year before last that I'm getting around to trying soon as well as a few others I picked up to try. I really wish I'd kept a record of what I've used in what. warm and white/natural have a more generous quilting allowance according to the instructions
