I use Warm and Natural 80/20 - tried Hobb's Poly down and it was good but very puffy when quilting. I recently purchased a roll of Pellon Nature's touch - it was on sale at Joann's and I had a 25% off purchase coupon too - the roll was 90" x 20 yrds for around $ 80. It was worth it to try - I haven't used it yet but its seems nice on the roll.
