This lace pattern reminds me of a refreshing slice of watermelon on a hot summer day. You could substitute many colors of yarn to represent different kinds of fruit. This sock could be made out of a multitude of different kinds of sock yarn, but the lace would show best in a solid or slightly semi-solid yarn.
Many people have a specific needle size they like for socks. I have a loose tension, so I knit on 2mm needles for sturdier socks. You may choose your favorite size, since the custom fit process is more important than actual gauge. You can try your sock on as you knit it. You may increase on the instep or sole edges as you like if the gusset or calves feel tight and the center lace pattern will not be disrupted.
For this pattern you customize the size as you go. You end toe increases when the toe barely touches the pinkie toe and you begin the heel flap when the instep of the sock touches the ankle bone. If you are making these for another person, you should measure the total foot length, length to ankle bone from toe, and foot circumference. The circumference of the knitted sock should be about ½-1 inch less than the actual foot circumference to keep the sock from sagging
