I just finished a baby quilt for a Corpus Christi, TX baby, and I used a 50/50 cotton/bamboo batting I got at Joann's. I am quite pleased with it! It is definitely lighter than warm and natural, my standard baby quilt batt, and it is very soft and drapable. It was a bonded batt so I didn't need close quilting which was nice because the quilt is a panel with circus animals, and I wanted the animals to stand out from the quilting. I used a fairly dense quilting for the backgrounds and only outlined the animals, and it came out nicely. I have only washed it once, but I like the results.
