My go to white is Legacy Studios (LS) Premium Muslin Bleached - the natural is good too. I usually purchase it when there is a 50% off coupon, like in the new flyer. I buy the 108" simply because it is more than double width and it is only $12.99 before the coupon. Nice tight weave, opaque, soft, and great drape. It is the same base fabric that all of the wonderful Legacy Studio prints are printed on. Great stuff.
