I usually buy warm and natural batting but ordered a roll of "soft 'n crafty" from JoAnn's. It is 90" wide by 25 yds and the price was very reasonable. It is a lighter weight batting and would be fabulous for a summer weight quilt or duvet. I have used some of it in the last table runner I just made and a couple of sets of mug rugs. I like it for the weight it is and it quilts very nicely. It has enough body to hold its shape, think you'd be happy with it. The item # I have is 12395943 so you might take a look. I ordered another brand also from a different place and it is just a tad heavier, can't find my invoice right now in my files but let me know and I can look it up for you if you're interested. I would be glad to send you a sample of this so you know what it's like DustysMomma if that would help you, let me know. Or if you just need some for your duvet, I'm sure we can work that out if you don't want a whole bolt of it.
