How to Knit Socks

There are many different ways you can knit socks. I have found that a top down sock with an afterthought heel to be the easiest beginner friendly way. Which is why I chose that construction for my cactus socks knitting pattern.

Steps to knitting a top-down sock.

  1. Cast on sock cuff stitches and join in the round.
  2. Knit the cuff and leg.
  3. Place waste yarn where the heel will later go.
  4. Continue knitting the foot.
  5. Decrease to shape the toe.
  6. Graft the toe stitches together.
  7. Place heel stitches onto kneedles.
  8. Knit the heel.
  9. Done!

How easy does that sound?!

Best Yarn for Knitting Colorwork Socks

There are a few things to keep in mind when choosing yarn for colorwork socks.

  1. Fiber Content: I find that using natural fiber yarn is best when knitting socks because it’s breathable and moisture wicking. This means your feet will sweat less and be more cozy. Also having a touch of nylon will make the yarn more durable. 
  2. Ply and Twist: Yarn made specifically for socks typically has a tight twist. This makes the socks more durable. It also keeps them from forming holes less quickly.
  3. Color and Value: Solid color yarns allow the colorwork design to stand out, whereas variegated yarns can sometimes get lost or muddy. If you want to use a variegated yarn I recommend making sure it is very different than the other color you are using in regards to it’s value. To understand this concept better I have a helpful video linked below.

Saguaro Blossom Socks – FREE Cactus Sock Knitting Pattern


The Saguaro is a majestic cactus that grows in the desert. Once a year these beautiful and protected plants blossom for less than 24 hours. The Saguaro Blossom Socks – a FREE cactus socks knitting pattern right here on the blog are a fun tribute to these cacti. Featuring staggered Saguaros with small blossoms throughout. These socks are knit from the top cuff down to the toes and feature an afterthought heel. A two color chart is used for the stranded color work.

Note: Floats

Be mindful of your floats while knitting. There are some sections where you may want to catch your floats so not to have a long strand running across the inside. I like to live dangerously and try not to catch as many floats as possible. You may find that you catch a toe when putting them on but I feel that I would rather carefully put on a sock than catch a million floats so I risk it! I leave this up to you the knitter to decide.

Note: Afterthought Heel

This sock is custom fit to your foot length. In order to get the proper fit I recommend knitting your heel before your foot is finished. This way you can easily try on your sock to get the best fit.

Saguaro Blossom Socks – FREE Cactus Socks Knitting Pattern Directions


With smaller needles and contrasting color, CO 60 (69, 78, 90) sts and join in the round, being careful not to twist your stitches.

Round 1: *K2, p1; rep from * to BOR. Continue in 2×1 ribbing until cuff measures 1″/2.5cm.

Next Round M + L only (S + XL move onto leg)

M: *K2, p1; rep from * to last three sts, k1, m1L, k1, p1. [1 st increased, 70 sts total]

L: *K2, p1; rep from * to last six sts, *k1, m1L, k1, p1; rep from * to BOR. [2 sts increased, 80 sts total]


Change to Gauge Needle.

Next, work rounds 1-36 of Chart. I like to separate each 10 sts chart repeat with stitch markers to keep me on track.


Knit the first round of the chart. On the second round of the chart repeat you will be placing the waste yarn for your afterthought heel. Knit across the first 30 (35, 40, 45) sts in the chart (round 2). Pick up your waste yarn and knit across the remaining 30 (35, 40, 45) sts in stockinette with your waste yarn.

Next, transfer all the sts you just knit with waste yarn from your right needle back to your left needle. Pick up your MC and knit across the waste sts you just knit.

Now your waste yarn is placed and you can continue knitting from the chart starting on round 2.


Continue knitting from the chart until your foot reaches your desired length. See page 4 for fit.

Note: Per the notes section, I like to knit my heel before I finish the foot and toe so that I can get the best custom fit. To do this, I knit one additional cactus section through round 18 and then knit my heel. Once my heel is finished I knit the rest of the chart until my desired length.


Once the foot reaches your desired length, pick up CC and smaller needles to knit your toe. See schematic on page 4 for the Craft Yarn Council standard foot lengths measured from the back of your heel to the end of the toe. You can also measure from your waste line, or if you are trying on your sock, the waste yarn line should line up with the center of your heel. I start my toe deacreases when the foot of my sock reaches the end of my pinky toe. See page 4 for diagram.

Next Round M + XL only

M: *K1, ssk, k32, k1, ssk, k to BOR. [2 sts decreased,  68 sts total]

XL: *K1, ssk, k42, k1, ssk, k to BOR. [2 sts decreased, 88 sts total]

Round 1: K1, ssk,  k 24 (28, 34, 38) sts, k2tog, k1, pm, k1, ssk, k 24 (28, 34, 38) sts, k2tog, k1.

Round 2: k

Round 3: k1, ssk, k to 3 sts before marker, k2tog, k1, slip marker, k1, ssk, k to 3 sts before BOR, k2tog, k1.

Repeat rows 2 and 3 until 24 (28, 32, 36) sts remain. Use Kitchener Stitch to graft toe sts closed. Kitchener Stitch video:


Your heel will be knit using smaller needles and CC. To begin you will first need to get your heel stitches back on your needles. You currently have half of your stitches knit onto a strand of waste yarn. Pick up those stitches above and below your waste yarn, plus an additional stitch at the end of each side, giving you 64 (74, 84, 94) total sts on your needles.


Make sure your sock is right side out when picking up sts. Start by picking up the stitch just before and below the beginning of your waste yarn. Then pick up the right leg of each stitch across bottom side of the waste yarn ending with the stitch just below and after where the waste yarn ends. Now you have the bottom half of your heel stitches picked up.

Repeat these steps for the stitches above your waste yarn. Once all stitches are picked up you can remove your waste yarn. I like to use the magic loop method for my heels and find moving my stitches onto the cord makes removing the stitches easier.

Next Round M + XL only

M: *K1, ssk, k34, k1, ssk, k to BOR.  [2 sts decreased, 72 sts total]

XL: *K1, ssk, k44, k1, ssk, k to BOR. [2 sts decreased, 92 sts total]

Round 1: k

Round 2: K1, ssk, k 26 (30, 36, 40) sts, k2tog, k1, pm,  k1, ssk, k 26 (30, 36, 40) sts, k2tog, k1.

Round 3: k

Round 4: K1, ssk, k to 3 sts before marker, k2tog, k1, slip marker, k1, ssk, k to 3 sts before BOR, k2tog, k1.

Repeat rows 3 and 4 until 24 (28, 32, 36) sts remain. Use Kitchener Stitch to graft heel sts closed. Weave in ends and block!
