This pattern is written to fit nearly all child sized feet. This particular pattern will fit a foot that is 4 inches (10 cm) up to 8 3/4 inches (22 cm) in length. That is a toddler size 1 up to a nearly adult size 5, in US sizing. Please note, this isn't a pattern for beginners, but if you know how to knit a stitch, pick up stitches and knit two stitches together, you should be okay. I've added a TON of photos to help you along with any of the more confusing parts. And please take note, you use 2 (two) sets of single point needles to make this. ¿¿¿¿¿¿¿ Because these are made for little feet, they often don't need much yarn and are quick to make. This makes them a great way to use up the smaller leftover bits from larger projects.
