This can be 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 pattern in a way even beginners can understand. There is a lace under the toe flap which helps in making the booties snug on tiny feet. Place a big button in place of the bow to give it an added edge. Use your imagination and make it your own.
