I love muslin...I use it often as I really love "30's quilts and it is great. I buy Kona which is usually about $7.99 a yard. I buy it by the bolt at Joann's when I have a 40% off or 50% off coupon. They have some muslin that is $1.99 a yard but it is very loosely woven and your can see through it...I have never tried it but am pretty sure it would shrink! I use the bleached and unbleached with great success!
