Yes it is. That's about the only cotton I use because it's made in the U.S.A. Thank you. They had some really pretty "Easter" colors a few weeks ago. The pink they had was called Strawberry Shortcake, the purple was called Sherbet, I believe, and the green was called Mint. But I can't get them all the time.
I knit dishcloths too, and would love to have this pattern if you'd like to share it. I gave all mine away as gifts. I agree with the made in USA... I do the same whenever possible.
