Wow, apparently all Bamboo batts are not created equally. I used a 50/50 bamboo/cotton batt (Koyoto) in the quilt in my avatar. I hand quilted it and totally loved it. I did not preshrink but washed it once the quilt was completed and dried it in the drier on the regular perma press cycle and it came out just beautiful. That quilt is so soft it just melts around you like butter. My daughter and Son-IL love it too.
