Two Easy Ways to Knit Socks on 2 Needles with a Seam

Knitting Socks on 2 Needles with a Seam is a great option for knitters who find working with double-pointed needles (a set of five needles) uncomfortable. For beginners, the traditional “grandmother’s method” of knitting socks in the round with five needles can be tricky—especially if your tension is loose, as the needles tend to slip out.

That’s why I recommend learning two simple methods that will help you knit socks on 2 needles with a seam with ease.

Knitting Two Socks at Once on Straight Needles (with a Seam)

To knit socks on 2 needles with a seam, you can use long straight needles or circular needles with a cable about 80 cm (32 inches) long. In this method, both socks are worked simultaneously on the same needles but from separate balls of yarn.

The number of stitches and rows for socks made with 4-ply sock yarn is shown in the table (Yarn with parameters of 100 g / 260 m. Knitting needles No. 3 have a Density of 24 n = 10 cm = 4 in)

Step-by-Step Instructions

1. First, knit the upper part of the sock, usually worked in ribbing, then continue in stockinette stitch. The length of the leg can vary—from knee-high socks to short athletic socks.
   To shape the heel, divide all stitches in half and work only one half to the heel height—about 3–7 cm (1.2–2.8 inches), depending on foot size (photo 1).
2. Next, divide the heel stitches into 3 parts and work only the center section. In every row (both right-side and wrong-side), knit the last stitch of the center section together with the first stitch of the side section (photo 2).
3. When all side stitches have been worked together with the center section, pick up along the sides of the heel the same number of stitches as were in the side sections. This will bring you back to the original stitch count (photo 3).
4. Continue knitting the foot to the desired length (photo 4).
5. About 2–3 cm (0.8–1.2 inches) before the end of the sock, begin shaping the toe. Divide the stitches into 4 sections. In every right-side row, decrease 1 stitch on both sides of each section until only 4 stitches remain on the needles (photo 5).
6. Cut the working yarn, leaving a 30–50 cm (12–20 inch) tail. Thread the remaining stitches onto the yarn, pull tight, and secure. Use the remaining yarn to sew the seam of the sock (photo 6).

Simple Toe-Up Socks on 2 Needles with a Seam

Socks on 2 needles with a seam are worked with an almost invisible knitted seam at the front and a neat, comfortable heel.

The pattern is written for three sizes.
Stitch pattern: Stockinette stitch (knit on RS, purl on WS).
Gauge: 26 stitches × 33 rows = 4 × 4 inches (10 × 10 cm).
Numbers in parentheses refer to teen and adult sizes; numbers before parentheses refer to a toddler (1.5–2 years).

How to Knit Socks on 2 Needles with a Seam (Toe-Up)

Make a loose chain loop with a crochet hook. From this loop, pick up 7 stitches onto a knitting needle: knit 1, yarn over, and so on.

Keep the chain loop loose so it doesn’t restrict the increasing number of stitches.

Row 1 (RS): edge st, yo, k1 repeated, end with yo, edge st (= 13 sts).
Row 2 and all even rows: purl all stitches (work yarn overs through the back loop).

In every odd row, increase 6 yarn overs evenly spaced until you reach the required stitch count for the foot width — 37 (43, 49 sts).

Row 3: edge st, yo, k2 repeated (= 19 sts).
Row 5: increase with yarn overs every 3 stitches (= 25 sts).
Row 7: increase every 4 stitches (= 31 sts).
Row 9: increase every 5 stitches (= 37 sts).

For larger sizes:
Row 11: increase every 6 stitches (= 43 sts).
Row 13: increase every 7 stitches (= 49 sts).

Continue straight in stockinette stitch to the heel.

Heel

Work the heel over the central stitches (more than half): 21 (25, 27 sts).

Row 1 (RS): edge st, knit to last heel stitch; do not knit the last stitch. Instead, insert the right needle into the corresponding stitch of the previous RS row, pull up a loop, place it on the left needle next to the stitch. Turn.

Row 2 (WS): purl to last stitch; repeat the same method using the previous WS row. Turn.

Continue working short rows, forming double stitches at each turn.

You should have 6 (7, 8) double stitches on each side and 9 (11, 11) center stitches.

Then begin expanding back:

Work across center stitches, resolving double stitches by knitting or purling them together.

Continue until the heel returns to 21 (25, 27 sts), with the first and last stitches being double stitches.

Leg

After completing the heel:

• Knit 12–14 rows in stockinette stitch, increasing 1 stitch in the last row.
• Then work 16–18 rows in ribbing (k1×p1 or k2×p2).

Finishing Socks on 2 Needles with a Seam

Without binding off the ribbing:

1. Drop the edge stitches along one side, unraveling the edge chain downward.
2. Use a crochet hook to join both edges:
   • Insert the hook into the first stitch of the opposite edge.
   • Pull through the corresponding loop.
   • Continue pulling loops through each other to recreate the edge chain.

This method forms a neat vertical seam without additional yarn.

At the top:

• Place the last loop back onto the needle.
• Bind off all stitches.
• Cut yarn and weave in ends.

Tighten the starting loop at the toe, secure, and weave in the tail.

Your socks on 2 needles with a seam are ready!
