Sea foam means sea foam, and that is exactly the color that this cotton is. I immediately fell in love with the color, but since I sometimes find (with glass beads) that colors are different in reality than in the online pictures, I hesitated. But that was unnecessary, because this color Sea Foam is exactly as it appears in the picture, although I had no idea that the cotton was sooooo wonderfully soft. Great yarn, and I'm looking forward to my summer top. I'll definitely be happy to shop here again!
