these, as our decorating theme for our little guy is sailboats. I think the yarn I made the first one was a cotton/acrylic blend (it was definitely washable) that is now discontinued, but I saw Knit Picks had a new Pima cotton/acrylic blend (Comfy), in lots of colors, I ordered it and even paid for shipping.
I wasn't sure if I wanted to have the main color be dark blue (as in my earlier version) or the lighter blue (as pictured in the pattern), so I got 2 balls of each. Then the natural for the sails, although I might change to the gold, and red for the flags.
The yarn is really, really soft. I usually shy away from acrylic (even small amounts in a blend) but I don't think I'm gonna mind this one. Now to quickly knit up some baby socks so I can cast on this hat!
