Prime Time December

This is a SKA challenge. It combines the Entrelac and the leftovers options. The pattern is inspired by an entrelac sock by Kathryn Anderson that was published in the Spin-Off sock book. Six colors of leftover yarn have been used. I may have to add another grey to finish the second sock. They're a birthday present for my daughter-in-law. Needles size US #1-2.25mm for the leg and US #1 1/2 - 2.5mm for the foot.
