How to cast on two-at-a-time socks on circular needles 🧦
Time to practice! Let’s knit, Beginner Sock Lover. In this new installment of our Guide to learn how to knit socks we teach several toe-up and cuff-down cast-on methods. Achieve seamless toes! We also tell you how to cast on two-at-a-time socks on circular needles. All with videos, tips, and tricks, and an even easier alternative to magic loop.
Toe-up cast-on
We recommend starting with toe-up socks on circular needles for 3 interesting reasons:
1. This type of construction is ideal to make the most of the ENTIRE ball if you wish. If you like, you can knit your socks as long as your yarn allows.
📌 If you knit high socks, keep in mind the diameter of your calves. Include some increases along the leg for the perfect fit.
2. Thanks to the cord of the circular needles, you can comfortably try on your socks as you go. Trying on your socks as you go provides an extra dose of confidence and motivation.
3. By starting your toe-up socks with Judy’s magic cast-on or the Turkish cast-on, you will achieve seamless toes.

The Turkish Cast-on creates an elastic and seamless base for the toe of your socks. Another advantage is that you’re wrapping directly with the working yarn, so you don’t need to leave a long tail to cast on stitches.

How to cast on socks two-at-a-time
We recommend knitting socks two-at-a-time to achieve the same result and, above all, to avoid Second Sock Syndrome. For this, you can use two balls; unravel one ball to make two smaller ones (one per sock); or knit one of the socks from the inside of the cake and the other from the outside.

📌 Second Sock Syndrome (SSS) is a humorous term used to describe the tendency sock knitters have to procrastinate or postpone finishing the second sock after completing the first. Behind Second Sock Syndrome lies a lack of novelty, motivation, or interest, as well as the temptation to cast on other more enticing projects.
