I use to work at House of Fabrics and the Kona solids that were sold were what is called seconds. Something you can see a slight off grain or maybe the color is slightly off from what is suppose to be or something else. If your are using Moda, I would check around and get a premium cotton on the internet or at your LQS. Hancock's of Paducah carries the Robert Kaufman Kona Cotton line. I keep White, Snow and Black always in my stash.
