I made these booties from the same pattern as the Ocean baby booties so you can get the pattern from there. They are made form a yarn which is 80% cotton and 20% acrylic and so they are machine washable and easy care. I really like the look and feel of this yarn because it has texture and some speckles. I made the booties to match the blue baby beanie. They are made on number 10 needles. I mixed some dark blue wool with the yarn when I was making the pompoms.
