A few years ago now, I did a non-scientific experiment with several brands of solid white fabrics. I did it because I was so annoyed with the fraying from Kona. My absolute favorite fabric is Art Gallery; Riley Blake Confetti is almost, but not quite, as smooth as AGF. In the end, Kona was the only one I absolutely will not use again. AGF is my favorite, and the rest were quite similar.
You can see my album here. Be sure to read the description under the title "Comparing Whites". Then, when you click on the pictures/videos, you'll see any more specific comments. This is posted in Facebook, but as it is a public album, you do not need to have a FB account to see it.
