Marshall's Dry Goods in AR now has a line of to-die-for solids called "Dream Cotton". It's the same thing as Moda Bella, even made at the same mill. The price is much more reasonable than Kona or Moda Bella... Only $3.99 a yard and they have dozens of colors. They will even send you a color swatch card to keep for reference. I LOVE the stuff and bought whole bolts the last time I was at Marshalls.
