I used it for a quilt for my Grandmother.
I didn't want anything too heavy (and that's relative for 100 pound 90 year old) for her lap and on her legs.
It's a big lap quilt - 72" square, but really weighs nothing, and she could easily fling it aside without effort.
It was longarm quilted, and it came out lovely. Not as "solid' as, say, a quilt with Warm&Natural cotton batting, but still great for the summer.
