I have only ever used W&N and am looking to expand my knowledge of different types of batting.

What else do you guys use? Why do you choose that batting?

100% cotton these days. Never use 100% poly for mine. See this post as to why: http://www.quiltingboard.com/t-56705-1.htm

I use to use 80/20% cotton/poly, but found it was cheaper to buy Warm and Natural from Jo-Anns with the 40% off coupon.... Less expensive is better and it is just as warm.

My favorite is warm and natural. The reason is because it's easy to find and I can use coupons on it so it's pretty cheap. A year or so ago, I found a bunch of packaged queen size w&n battings at Joann's for about $5. I bought them all (sorry-I'm greedy!).

I love Mountain Mist White or Cream Rose. It's thin and easy to use. I can get an antique look to my quilts, or an cotemporary look if i want. It is expensive though. I use the Hobby Lobby coupons to get it. Or stock up when it's on sale. I use Warm and Natural when I want a heavier quilt.

I love using Quilters Dream Blend (70/30) for my machine quilting. It is soft, drapes well and quilts up nicely. I also like the puffiness or antique look from it when i wash it. You can also quilt up to 12" apart.

I use W&N. I have never used anything but cotton batting, for one thing W&N you can quilt up to 10 to 12 inches apart, and with so many allergies out there and I want they people I give them to to be able to enjoy them. Especially baby quilts.
I tried a poly once than my MIL gave me and it was a disaster!! Never again!

I only use Warm and Natural if it is my money buying it. lol
I am working on a quilt for my sister, she bought all the materal needed, and quilting it with Mountain Mist. It is a soft batting but I don't know if I like it or not. lol

I use many differnent battings... it is really very project specific.
I have used wool, bambo, poly, poly/cotton, cotton... all from differnent manufactures with various percentages of fiber content. Some I preshrink .. some I do not. I evaluate each project as the final outcome I want is diffenent. The only one I have not tried is silk. Sometimes I double batt and use two different types.

I used Warm and Natural in two quilts. I thought they were stiff as boards. I started using Hobbs 80/20 after that and I'm still using it. I really like the way it gives your quilting some definiition and it drapes really nice. I also like all the different Quilter's Dream battings. The cotton is wonderfully soft and very drapable. Dream Poly the only poly batting I'll use.

have only ever used warm and natural With coupons from Joanns I get it every chance I can at half price. My sil bought a whole bolt of it, she'll never run out
