The Wildling Fern Sock: A Free Knitted Botanical Ankle Sock Pattern

Wrap your feet in the untamed beauty of the forest floor with these knitted ankle socks, featuring a cascading fern cable that climbs the outer edge and a soft, squishy ribbed cuff. This pattern is a love letter to woodland wanderers, blending cozy warmth with intricate botanical texture. Whether you're curled up by a fire or hiking through autumn leaves, these socks bring a touch of wild elegance to every step.

This free pattern is designed for adventurous beginners and intermediate knitters alike. The fern cable looks complex, but once you master the simple C4F and C4B stitches, the rhythm becomes meditative and rewarding. Let's dive into creating your own pair of botanical treasures.

Materials Needed

Before you begin, gather the following supplies to ensure a smooth knitting experience:

• Yarn: Fingering weight yarn (e.g., Malabrigo Sock in 'Pine Grove' or a similar wool/nylon blend), approximately 350-400 yards. The wool/nylon blend adds durability for socks, while the wool provides warmth and stitch definition.
• Needles: US Size 1.5 (2.5 mm) double-pointed needles (DPNs) or a circular needle for the magic loop method, plus a cable needle for the fern pattern.
• Notions: Stitch markers (at least 4), a tapestry needle for weaving in ends, and scissors.

Gauge: 32 stitches and 44 rows = 4 inches in stockinette stitch, after blocking. Achieving the correct gauge is crucial for a proper fit, so take time to swatch!

Sizing: This pattern is written for a women's medium (US shoe size 7-8.5). To adjust the size, you can change needle size (larger needles for bigger feet, smaller for petite) or adjust the stitch count in multiples of 4 for the ribbing and cable pattern.

Step-by-Step Instructions

This pattern is worked from the cuff down with a heel flap and gusset. Let's break it down into manageable sections.

Abbreviations

• k = knit
• p = purl
• k2tog = knit two together (right-leaning decrease)
• ssk = slip, slip, knit (slip two stitches knitwise, then knit them together through back loops – left-leaning decrease)
• c4f = cable 4 front (slip 2 stitches to cable needle, hold in front, k2, then k2 from cable needle)
• c4b = cable 4 back (slip 2 stitches to cable needle, hold in back, k2, then k2 from cable needle)
• m1l = make one left (pick up bar between stitches from front to back, knit through back loop)
• m1r = make one right (pick up bar between stitches from back to front, knit through front loop)
• pm = place marker
• sm = slip marker

Cuff

Cast on 64 stitches. Distribute evenly over 4 needles (16 stitches each) if using DPNs, or use the magic loop method with a long circular needle. Join in the round, being careful not to twist your stitches.

Rounds 1-12: Work *k2, p2* ribbing for 12 rounds. This creates a stretchy, snug cuff that will keep your socks in place.

Leg

Now we'll set up the beautiful fern cable pattern. The cable will be worked on the outside of the leg (needles 1 and 4 if using DPNs, or the first 32 stitches on the magic loop).

Round 1: *K2, p2* across the instep (first 32 stitches), then work the fern cable chart over the next 16 stitches (the 'outside' of the leg), and *p2, k2* across the remaining 16 stitches (the 'inside' of the leg).

Fern Cable Pattern (worked over 16 stitches, repeated every 12 rounds):

• Rounds 1-4: K4, p2, k4, p2, k4
• Round 5: C4F, p2, C4B, p2, C4F
• Rounds 6-8: K4, p2, k4, p2, k4
• Round 9: K4, p2, C4F, p2, k4
• Rounds 10-12: K4, p2, k4, p2, k4

Repeat these 12 rounds until the leg measures 5 inches from the cast-on edge, ending with round 12. The cable will naturally spiral and twist, creating that gorgeous fern-like texture.

Heel Flap

The heel is worked back and forth over the last 32 stitches (the inside of the leg). Place the instep stitches (the 32 stitches with the cable) on hold – you can leave them on the needle or use a stitch holder.

Row 1 (RS): *Slip 1 purlwise, k1* repeat across all 32 heel stitches.

Row 2 (WS): Slip 1 purlwise, purl across all heel stitches.

Repeat these two rows until the heel flap measures 2.5 inches, ending with a WS row. The slipped stitches create a reinforced, durable heel that will withstand wear.

Turn Heel

Now we'll shape the heel cup with short rows. This creates a comfortable, anatomical fit.

Row 1 (RS): K18, ssk, k1, turn.

Row 2 (WS): Slip 1 purlwise, p5, p2tog, p1, turn.

Row 3: Slip 1 purlwise, knit to 1 stitch before the gap, ssk, k1, turn.

Row 4: Slip 1 purlwise, purl to 1 stitch before the gap, p2tog, p1, turn.

Repeat rows 3 and 4 until all heel stitches are worked, ending with a WS row. You should have 20 stitches remaining on your needle. The "gap" refers to the space created by the turning – you'll knit or purl until just before that gap, then decrease.

Gusset

With the right side facing, knit across the 20 heel stitches. Now we'll pick up stitches along the heel flap edges to create the gusset.

Pick up and knit 16 stitches along the left side of the heel flap. Place a marker. Work the instep stitches in pattern (continue the fern cable as established). Place a marker. Pick up and knit 16 stitches along the right side of the heel flap. Knit the remaining 10 heel stitches. You now have 84 stitches total.

Decrease Round: Knit to 3 stitches before the first marker, k2tog, k1, sm. Work instep in pattern. Sm, k1, ssk, knit to end of round.

Next Round: Knit all stitches (no decreases), working instep in pattern.

Repeat these two rounds until you have 64 stitches remaining (32 for instep, 32 for sole). The gusset decreases shape the sock to fit comfortably around your arch.

Foot

Continue working in the round, keeping the instep in the fern cable pattern and the sole in stockinette stitch (knit all stitches). Work until the foot measures 2 inches less than the desired total foot length. For example, for a size 8 foot, knit until the foot measures 7 inches from the heel. This allows room for the toe shaping.

Toe

Time to shape the toe with gentle decreases for a rounded, comfortable fit.

Round 1: K1, ssk, knit to 3 stitches before marker, k2tog, k1, sm, k1, ssk, knit to 3 stitches before end of round, k2tog, k1. (4 stitches decreased)

Round 2: Knit all stitches.

Repeat these two rounds until 32 stitches remain. Then decrease every round until 16 stitches remain. The toe will taper beautifully, hugging your toes without being too tight.

Cut yarn, leaving a 12-inch tail. Thread the tail through a tapestry needle, slip the remaining stitches onto the needle, pull tight, and weave in the end. This creates a seamless, invisible toe closure.

Finishing

Repeat the entire process for the second sock. Once both socks are complete, weave in all loose ends and block them gently. Blocking will open up the cable pattern, making the fern leaves crisp and defined.

To block, soak the socks in lukewarm water with a gentle wool wash, then gently squeeze out excess water (never wring!). Lay flat on a towel, shaping to the correct dimensions, and allow to dry completely.

Your Wildling Fern Socks are now ready to wear! Slip them on and feel the forest floor beneath your feet – cozy, textured, and utterly beautiful. Happy knitting!
