Because the indigo vat is a living, changing thing some days yield more intense color than others. I was particularly happy with how this batch of cotton took the color. The color had really rich tones and the darkest blue is almost black. This is a percale cotton which folds easily and sharply and gives very crisp lines and an interesting variation of color. It's a very tight weave which makes it easier to seal off the white areas and not have that shadowy, hazy line quality that you get with Kona cotton. It's a good weight for quilting, and I think this square can be cut up into some interesting squares for piecing.
