I suggest that after making the squares, you select a neutral yarn to sew the squares together (I used mattress stitch) and for the border (I used a neutral then did a few rounds of the yarn I used for squares to create a small stripe in the border.)
The sock for my self-imposed sock club is moving forward, slower than I want, but at least it's progressing. I am working on a few designs currently and that mindwork is taking some of my free knitting time. What a luxury; to get to knit as fun, and when it's time to work, to get to knit some more! Speaking of which, time to get back to my pattern design knitting... (which I will talk about just as soon as I'm allowed!)
Happy Knitting,
Kyle
