Darlene, I started quilting a year ago with Joanne's 80-20 figuring that was all my quilts were worth and it worked great. I got lured into the warm and natural thing, but couldn't get the real difference except for the shrinkage. Then I tried Quilters Dream (because I had to buy from my quilt store fore a class) and I used the 100% cotton lightweight/standard and it was very soft and quilted farther apart than I would have thought and it did not drape like an 'industrial quality' quilt. Have not tried Hobbs. There are times when you can say you used 100% cotton and it makes people happy!
I have no interest in reused coke bottles or bamboo (I once saw bamboo completely cover and destroy an out-of-commission automobile and as a gardener I respect its powers)
I am at the stage in quilting where I don't know if my humble efforts are worth the extra cost to go high-end, but batting has not been the choke-factor in my 2011 cost analysis - it was thread!

I've used warm and natural and the batting. Being on a fixed income I cant always afford the warm and natural, ba

I have used Dream Green for almost all of my quilting projects. One time, my LQS didn't have it in stock and I used Warm and Natural and didn't care for the way the quilt looked after I washed it.

I love the bamboo batting from fairfield, its hypo-allergenic and its lots lighter in weight than warm and natural, for instance, when you have a queen size quilt of warm n natural, it weights your toes down. Bamboo does not, also with warm n natural, I need a blanket underneath, not so with the bamboo. I guess since its mixed with cotton, it shrinks like the cotton does, I dont see any difference! good luck with your poll.

I really like the Hobbs 80/20. I like the way it makes finished quilt feel, the weight of the quilt, the way it sews and the way it "puckers" when washed. do a search to get other views. Also my LQS owner said not to use Warm and Natural due to the small cotton seeds that are left in the batting since they will eventually "weep" their oil out into the quilt. I have never used it because of that reason.

as a long armer my favorites are warm and natural and warm and white - I absolutly hate mountain mist when it hangs down the weight of it makes it seperate and come apart it is very difficult to handle as well on the long arm.

I used to use Warm & Natural, but I've been using more of either Hobbs 80/20, or Luna (by Moda), in particular their bamboo blend Kyoto.

I use Hobbs Polydown for all of my kid friendly and heavy use, frequent wash quilts because it is affordable, quilts easily and washes and dries well. I buy it by the 30 yard roll (last roll $160 in Canada). I also use Hobbs 80/20 and W&N in family quilts that won't be dragged around and it's at least double the price of the Polydown.

batting preferences
 

I use several warm and natural/white is the one I use for most of my quilts. I also like the warm blend that I get from Joanns by the bolt and is available in 90" and 108/110 inches wide and about half the price. I use this a lot in donated quilts since it is the 50/50 blend and gives the best of both worlds. It also has a little more loft to it when it is quilted than warm and natural.

Bamboo and wool bat are excellent but price wise not an everyday use for me since I give many of my quilts as gifts and they are well used.

Nearly all my full size quilts are at least 90 wide so the 90 wide batting is not quite big enough to do one piece. So the wider width is a must for me.

I am a hand quilter, and the only thing I will use is Mountain Mist Quilt Lite. It quilts so much easier than cotton batting of any kind. The stitches stand out very well, and it is easy to get tiny ones. I usually buy it when JoAnn's have their batting at half off, and I also have another 10% off coupon so it makes it very reasonable. Machine quilting for me is for the birds. I can't do it. Most of mine now go to a long armer because I have so may tops I will never get them quilted by hand.
