Inspiration & Design

When it comes to crochet socks people are divided. Not me, I love both crochet and knit socks. If you want to read more about my sock-pinion I have several blog posts that might be worth your while.

Speaking of blog posts, for the past 2 years I’ve released a sock for Socktober and though this one is a little later in the month, it’s been living rent free in my head for a while.

A while back I had submitted a design for a winter 2021 publication. While it was denied I was still very excited to work the sock up. Almost a year, Yikes. Anyway, the submission call centered on plaid and I wanted to create something simple, fun and with colors.

There are many different takes on a “plaid” design. By definition plaid is a rectangular garment or piece of cloth, usually made of the checkered material called tartan. Scottish friends please correct me.

While my inspiration came from this, these simple colorwork socks are more of a grid design. It’s because of the grid design that I have named these the Squared Root socks.

Simple and stylish.

PS. Am I know listening to Celtic music… I will neither confirm or deny

The Yarn

I believe I already established that this design lived in my head rent free. Well, when Kathryn of Crafternoon treats announced that she had some hanks of her Christmas colorway left, I snagged one. Maryushka The Firebird is a gorgeous yarn with a butter yellow base and an amazing range of autumnal speckling. From golds, forest greens to maroon the yarn just sparks Autumnal joy.

Because of said Autumnal vibes, I thought Sphene from Socks Yeah! was the perfect compliment. Perhaps a little too perfect. Sphene does make the colorwork more subtle but I like it all the same.

Although both of these yarns are classified as fingering weight, their thicknesses vary. WPi for Maryushka is between 22 & 23 , while Socks Yeah is 26 wpi (wraps per inch).

What does this mean for the sock? Well, I found the socks yeah yarn to have less stretch so it helps the sock tuck in nicely. While the socks are different thicknesses I enjoyed crocheting with both of them.

If you are interested in yarn reviews, message me and I shall start writing more blog posts reviewing yarns.

Simple Colorwork Socks

The socks are crocheted toe-up using a contrasting color for the toe and heel flap. The simple colorwork is featured on the leg of the sock and forms a grid design. The sample shown is crocheted following the instructions for size 2. Size 2 uses 61g of the main color and 20g of the contrasting color. Of course, this is subjected to gauge matching.

The pdf pattern includes a video tutorial to help you on your simple colorwork sock making journey.
