It's all I use now for customer quilts. The only other batting I ever use is Hobb's Heirloom wool. Warm Company says it's 50% thicker than W&N. I find it provides great stitch definition & is wonderful for faux trapunto or nice heavy quilts. Since it is truly 100% cotton (no scrim), it does crinkle more than W&N and is more of a challenge to keep the quilt flat during DSM quilting process -- that's not a concern of mine since I wash mine to crinkle them later anyways. It is cozy & fluffy & absolutely wonderful for baby quilts. When I have time (not sure when that will be), I hope to make myself a lap quilt with it as it is super soft & cuddly.
You do not pre-soak it like W&N since it is only needle-punched & has no scrim, or else it would fall apart in the water, but I have severe allergies to all sorts of chemicals/materials & have not had any issues with W&N. I have quilted as close together as 1/4" for some designs (with an average spacing of 3/4" between quilting lines) with 100% cotton Aurifil thread & am very, very happy with the results.
I bought mine on a 25yd roll from walmart.com with free shipping. It was cheaper even than buying at JAF with 60% off coupons.
