This is the first pattern I actually wrote. I started this as a girl's pattern and realized that just with a few changes, it can be adapted for a boy. There is a lace under the toe flap which helps in making the booties snug on tiny feet.
This was worked using worsted weight yarn and hooks H and F to fit ages 0-3 and 3-6 months. To make bigger sizes you will have to use a hook I too. Pattern is written for sizes 0-3, 3-6, 6-9 and 9-12 months. Picture of every step is included in the pdf in a way even beginners can understand. I was using the leftover yarn I had and I think the purple should have been a tad brighter. The black one looks lovely but the picture fails to capture its real beauty. Place a big button in place of the bow to give it an added edge. Use your imagination and make it your own.
