Martha Socks: A Beautiful Free Lace Sock Pattern for Ladies
There is something deeply satisfying about slipping on a pair of hand-knitted socks. The way the fabric hugs your foot, the warmth that radiates from yarn worked stitch by stitch with your own two hands — it is a feeling that store-bought socks simply cannot replicate. And when those socks happen to feature a delicate lace pattern that catches the light and draws the eye, the experience becomes even more special. That is exactly what the Martha Socks pattern is all about.
Whether you are a seasoned sock knitter looking for a fresh project or someone who has knitted a few pairs of plain stockinette socks and is ready to take the next step, the Martha Socks pattern is a wonderful choice. It is elegant without being fussy, detailed without being overwhelming, and best of all, it is completely free. In this post, I am going to walk you through everything you need to know — the inspiration behind the pattern, the materials you will need, tips for working lace in the round, and a full breakdown of how to knit these beautiful socks from cuff to toe.
Pull up a chair, make yourself a cup of tea, and let us talk about all things Martha.
The Inspiration Behind Martha Socks
Every pattern has a story, and the Martha Socks pattern is no exception. The name Martha evokes a sense of quiet elegance and timeless femininity — the kind of woman who sets a beautiful table, keeps a tidy home, and still somehow finds time to sit by the window and knit. Whether you picture a grandmother who smelled of lavender and kept an overflowing basket of yarn beside her armchair, or simply a woman who appreciates beautiful, handmade things, the spirit of Martha is woven into every row of this pattern.
The lace design itself is inspired by traditional Shetland and Estonian lace traditions, both of which have a long and celebrated history of producing fine, delicate knitted fabric. Shetland lace, in particular, is famous for its featherweight shawls and intricate motifs — pieces so fine that an entire shawl could be drawn through a wedding ring. While the Martha Socks are not quite that extreme, they carry forward that tradition of using simple yarn-over and decrease combinations to create something that looks far more complex than it actually is.
Lace on socks might seem intimidating at first, but once you understand that sock lace is almost always worked on a smaller scale and with fewer rows to memorize than a shawl, you will find it surprisingly approachable. The Martha pattern uses a repeat that is easy to memorize after just a round or two, which means you can knit it while watching television, chatting with friends, or riding as a passenger on a long car trip.
Materials and Yarn Suggestions
Before you cast on, let us talk about what you will need to gather.
Yarn: The Martha Socks pattern is designed to be worked in fingering weight sock yarn, also known as 4-ply yarn in many parts of the world. You will need approximately 350 to 400 yards for a women’s average size foot, so one standard 100-gram skein of sock yarn will usually be sufficient, though it is always a good idea to have a little extra on hand just in case. For the lace to show its best, choose a smooth yarn with good stitch definition. Heavily textured, fuzzy, or thick-and-thin yarns will obscure the lace motifs and make the pattern harder to read as you knit. Solid colors and semi-solid colorways tend to show lace beautifully, though a very gentle gradient can also look stunning. Avoid busy multicolors or variegated yarns unless you specifically love the scrappy, energetic look they produce, since they will compete with the lace design.
Some lovely yarn options to consider include Malabrigo Sock, which has incredible depth of color and a smooth ply; Hedgehog Fibres Sock, which is hand-dyed and absolutely gorgeous; West Yorkshire Spinners Signature 4-ply, which is wonderfully affordable and comes in a huge range of colors; or the classic Regia 4-ply if you want something sturdy and widely available. Any superwash-treated sock yarn will work, and the nylon content common in most sock yarns will add durability to the finished fabric.
Needles: You will need a set of double-pointed needles or a long circular needle for the magic loop method, or two shorter circular needles if that is your preferred technique. The recommended needle size is 2.25mm (US1), though as always with knitting, your gauge is far more important than matching the needle size exactly. Knit a small swatch and adjust your needle size accordingly.
Gauge: The pattern is written for approximately 36 stitches and 48 rows to 10 centimeters (4 inches) in stockinette stitch, measured after washing and blocking. Because the lace portions of the sock are worked with yarn overs, the gauge may vary slightly in those sections, but the heel and foot are worked in standard stockinette, which gives you a reliable reference point.
Other notions: You will need a tapestry needle for weaving in ends, a stitch marker or two, and scissors. A row counter, either physical or app-based, can be helpful when you are first learning the lace repeat, though most knitters find they no longer need it once the pattern is memorized.
Sizing
The Martha Socks pattern is written for a women’s average foot with a foot circumference of approximately 8 inches (20cm) and is easily adjustable for other sizes. To make the socks smaller or larger, you can adjust the number of stitches in the cast-on, keeping in mind that the lace repeat is worked over a multiple of a specific number of stitches, which will be specified in the pattern notes. As a general rule, socks should be knitted to approximately 10 percent negative ease, meaning the sock circumference should be about 10 percent smaller than the actual foot circumference so that the fabric stretches to fit snugly.
For foot length, the pattern provides instructions for adjusting the length of the foot before you begin the toe decreases, making it easy to customize the sock for any foot length simply by knitting more or fewer rounds before shaping.
Understanding the Lace Pattern
The lace motif in the Martha Socks is a classic eyelet vine, a flowing design that travels up the leg of the sock in a gentle diagonal, giving the impression of a climbing plant or a winding ribbon. It is worked over an 8-stitch repeat and an 8-row repeat, which makes it beautifully symmetrical and satisfying to execute.
The basic building blocks of any lace pattern are yarn overs and decreases. A yarn over creates a new stitch (and therefore a hole) by wrapping the yarn around the needle between two other stitches. A corresponding decrease — usually a knit two together (k2tog) or a slip, slip, knit (ssk) — removes a stitch to maintain the overall stitch count. By placing these yarn overs and decreases in different positions across multiple rows, lace creates its characteristic organic, flowing look.
In the Martha pattern, the yarn overs lean consistently in one direction across the row, creating that lovely diagonal vine effect. The decreases are worked as ssk on one side and k2tog on the other, which mirrors the lean of the decreases and keeps the edges of the lace motif clean and defined.
If you have never worked a yarn over in the round before, the technique is simple. When you reach the position in the pattern where a yarn over is called for, simply bring your yarn to the front of the work (as if to purl), and then knit the next stitch as normal, carrying the yarn over the needle as you do. That loop sitting on your needle is your yarn over, and on the following round, you will treat it as a regular stitch.
One tip that makes a big difference in the quality of hand-knitted lace: always read ahead in the pattern before you start a row or round. Understanding where you are headed — which stitches will be yarn overs, which will be decreases — helps you catch mistakes before they become problems. If your stitch count is off at the end of a repeat, stop and check before continuing, as mistakes in lace can be tricky to trace back if you knit past them.
The Pattern: Martha Socks
Note: This pattern is written for a women’s medium (foot circumference approximately 8 inches/20cm). Instructions for adjustments are included in the notes.
Abbreviations:
CO — cast on; k — knit; p — purl; k2tog — knit two together; ssk — slip, slip, knit (a left-leaning decrease); yo — yarn over; pm — place marker; sm — slip marker; w&t — wrap and turn; rep — repeat; rnd — round; RS — right side.
Lace Repeat (worked over 8 stitches, 8 rounds):
Round 1: k1, yo, k2, ssk, k2, k2tog, k1, yo; rep from to end of repeat section.
Round 2 and all even rounds: Knit.
Round 3: k2, yo, k1, ssk, k1, k2tog, k1, yo, k1; rep from .
Round 5: k3, yo, ssk, k2tog, yo, k2; rep from .
Round 7: k2, k2tog, yo, k1, yo, ssk, k2; rep from .
Round 8: Knit.
These 8 rounds form the lace repeat. Continue working them in sequence up the leg of the sock.

Step-by-Step Construction
Cuff: Cast on 64 stitches using your preferred method. The long-tail cast on works beautifully for socks and produces a tidy, stretchy edge. Join to work in the round, being careful not to twist your stitches, and place a marker to indicate the beginning of the round. Work in a 2×2 rib (k2, p2) for 8 rounds or approximately 1 inch. This creates the gentle elasticity at the top of the cuff that keeps the sock in place on the leg.
Leg: After completing the cuff, begin working the lace repeat across all 64 stitches. Continue until the leg measures approximately 6 to 7 inches from the cast-on edge, or your desired length. The lace pattern is worked on all stitches around the leg, creating that beautiful all-over lace look that is the hallmark of this design.
Heel Flap: Place 32 stitches on hold for the instep (these will sit at rest while you work the heel). The remaining 32 stitches form the heel flap. The heel of the Martha Socks is worked as a classic heel flap and gusset, which is the most traditional and arguably the most durable construction for a knitted sock. The heel flap is worked back and forth in rows in a slip-stitch pattern: sl1, k1; rep from across on right-side rows, and sl1, purl to end on wrong-side rows. Work 32 rows total, or until the heel flap is approximately square.
Heel Turn: Turn the heel using a standard short-row heel turn. This creates the curved cup of the heel that fits snugly around the back of your foot. Detailed row-by-row instructions are included in the pattern PDF, but the basic sequence involves a series of short rows that gradually consume the stitches from the edges of the heel flap toward the center.
Gusset: Pick up stitches along both sides of the heel flap and work gusset decreases every other round until you return to 64 stitches. During the gusset, the instep stitches continue in the lace pattern as established, while the sole stitches are worked in plain stockinette. This is one of the most satisfying parts of sock construction — watching the shape of the sock emerge as you work the gusset decreases.
Foot: Continue working until the foot measures approximately 2 inches less than the desired total foot length, keeping the lace pattern on the instep and stockinette on the sole. This is where you will want to try the sock on frequently to check the length, and where you will make any adjustments for a custom fit.
Toe: Work the toe using a standard wedge toe decrease. Decrease every other round until 32 stitches remain, then decrease every round until 16 stitches remain. Graft the remaining stitches together using Kitchener stitch for a smooth, invisible join. If you have never worked Kitchener stitch before, do not be intimidated — there are excellent video tutorials online, and it becomes second nature after you have done it once or twice.
Blocking Your Finished Socks
Blocking is the step that transforms a finished knitted piece from something that looks a bit cramped and uneven to something that lies flat, opens up, and shows its true beauty. For lace especially, blocking is not optional — it is essential. The yarn overs in the lace pattern will not fully open until they have been wet-blocked and pinned or stretched into shape.
To block your Martha Socks, soak them in cool water with a small amount of wool wash for about 20 minutes. Gently squeeze out the excess water (never wring or twist), roll them in a clean towel to remove more moisture, and then insert sock blockers if you have them, or simply lay the socks flat on a blocking mat or clean towel. Gently stretch the fabric to open up the lace, and allow the socks to dry completely before wearing or photographing them.
The difference blocking makes is remarkable. What looked like a muddy, compressed tangle of loops before blocking will emerge as a clean, defined, delicate pattern. Give your socks this final step — they deserve it.
Tips for Success
A few additional thoughts to set you up for a wonderful knitting experience with this pattern. Work the lace slowly at first. There is no race, and slow, careful attention in the early rounds will pay dividends later. Once the pattern is in your hands and fingers, it will speed up naturally.
Keep your tension even and relaxed. Tight knitters sometimes struggle with lace because the yarn overs end up too small and difficult to work into on the following round. If this is a tendency of yours, try going up half a needle size on the leg and reverting to your usual size for the heel and foot.
Use lifelines. A lifeline is a length of smooth, contrasting yarn threaded through all your live stitches at the end of a complete repeat. If you make a mistake and need to rip back, the lifeline catches your stitches and prevents you from dropping below the last good row. For lace knitting, lifelines are a genuine act of self-care.
Finally, enjoy the process. Sock knitting is one of the most portable and companionable of all knitting projects. The Martha Socks will travel with you, wait patiently in your bag, and reward every hour of attention you give them with something beautiful and lasting.
