Seafarers Heart Knitted Pillow: Free Knitting Pattern

There is something deeply satisfying about a knitting project that combines timeless nautical charm with a symbol as universally beloved as the heart. The Seafarers Heart Knitted Pillow does exactly that — bringing together cable textures, rope-inspired details, and a central heart motif into a pillow that feels both coastal and cozy, rugged and romantic. Whether you are decorating a beach house, adding warmth to a lakeside cabin, or simply want a statement cushion for your living room sofa, this pattern delivers the kind of handmade character that no store-bought pillow can replicate.

This free knitting pattern is written for confident beginner to intermediate knitters. If you have completed a few simple projects and feel ready to try basic cables and a touch of colorwork or textured patterning, you are in exactly the right place. By the end of this post, you will have everything you need — materials, abbreviations, gauge, and row-by-row instructions — to knit your own Seafarers Heart Knitted Pillow from cast-on to finishing.

The Story Behind the Design

The seafarers heart is a motif with deep roots in maritime folk art. Sailors would carve hearts into whalebone, embroider them onto garments, and knit them into warm woolens as tokens of love and longing for the people waiting for them at home. The “sweetheart pillow” tradition, where sailors brought back handmade cushions as gifts from distant shores, inspired this design. Reimagined here in a modern knitting pattern, the seafarers heart blends that heritage with contemporary home décor sensibilities.

The pillow features a raised heart at its center, surrounded by rope cable panels that frame the design on either side, and a clean seed stitch border that keeps the whole composition grounded. It is the kind of project that looks far more complex than it actually is — which, frankly, is the best kind of knitting project there is.

Materials You Will Need

Before casting on, gather everything on this list. Having your materials ready before you begin saves interruptions mid-project and helps you get an accurate gauge swatch.

Yarn: Approximately 200–250 yards of worsted weight yarn (also labeled as Aran weight in some countries). The original sample uses a natural oatmeal or cream-colored wool, which gives the cable and heart textures maximum definition. Solid or heathered neutral tones work best for showing off textured stitches, though a deep navy or soft slate blue would give the pillow a striking nautical feel.

Needles: US size 7 (4.5mm) straight or circular knitting needles. If you tend to knit tightly, go up half a size. If you knit loosely, try going down half a size and recheck your gauge.

Cable needle: One standard cable needle or a spare double-pointed needle.

Pillow insert: A 16 x 16 inch (40 x 40 cm) pillow insert. Slightly overfilling the cover gives it a plump, professional finish, so if you can find an 18-inch insert to stuff into a 16-inch cover, even better.

Tapestry needle: For weaving in ends and seaming the front and back panels together.

Stitch markers: Optional but helpful, especially for marking the boundaries of the central heart panel.

Buttons or zipper (optional): If you prefer a removable cover, three or four large wooden or shell buttons along one seam give the pillow an authentically nautical look.

Gauge

18 stitches and 24 rows = 4 inches (10 cm) in stockinette stitch on US size 7 needles.

Please do not skip your gauge swatch. Pillow sizing depends on it. Knit a swatch of at least 5 inches square in stockinette, wash and block it the same way you plan to treat the finished pillow, then measure. Adjust your needle size as needed before committing to the full project.

Finished Measurements

Approximately 16 x 16 inches (40 x 40 cm) after blocking and finishing.

Pattern Notes

This pattern is worked flat, meaning you knit back and forth in rows rather than in the round. You will knit two identical panels (or one identical and one plain, if you prefer a simple stockinette back), then seam them together around the pillow insert.

The heart motif at the center is created using a combination of reverse stockinette (purled bumps against a knit background) on right-side rows, which raises the heart shape above the surrounding fabric and gives it a sculptural quality. You can substitute a simple intarsia heart in a contrasting color if you prefer a color-pop approach, but the textured version is what makes this pillow feel truly handmade and heirloom-quality.

Read through the entire pattern once before beginning. It sounds like standard advice, but with a project that combines a cable panel, a textured heart, and a seed stitch border, a preview pass saves a lot of confusion.

The Knitting Pattern

Cast On

Using US size 7 needles and your chosen worsted weight yarn, CO 74 stitches using the long-tail cast on method. This gives a firm, even foundation edge that will seam neatly.

Seed Stitch Border (Bottom Edge)

Rows 1–6: K1, p1; rep from to end of row.

This creates the seed stitch border at the bottom of the pillow. Seed stitch is wonderfully forgiving and gives a tidy edge that lies flat without curling — essential for a pillow front that needs to look crisp.

Body of the Pillow

The body of the pillow is divided into three vertical sections across the width of your work: a left rope cable panel, a central heart panel, and a right rope cable panel. Seed stitch columns of 4 stitches each separate these sections.

The stitch distribution across your 74 stitches reads as follows from left to right: 4 seed stitch border sts, 10 rope cable sts, 4 seed stitch separator sts, 38 central heart panel sts, 4 seed stitch separator sts, 10 rope cable sts, 4 seed stitch border sts.

Place markers to separate these sections after your first setup row if it helps you track them.

Setup Row (RS):

K1, p1, k1, p1 (seed st border), p2, k6, p2 (left cable panel), k1, p1, k1, p1 (seed st separator), k38 (central panel), k1, p1, k1, p1 (seed st separator), p2, k6, p2 (right cable panel), k1, p1, k1, p1 (seed st border).

Rope Cable Pattern (worked over 10 sts: p2, k6, p2)

The rope cable is a classic four-stitch cross cable, worked over the center 6 stitches of each 10-stitch panel. The purl stitches on either side of the cable give it that crisp, raised-ridge look you see on traditional Aran and fisherman sweaters.

Cable RS Rows (work cable cross every 6th RS row):

P2, C6F (slip 3 sts to cable needle, hold in front, k3, k3 from cable needle), p2.

Cable WS Rows:

K2, p6, k2.

Non-cross RS Rows:

P2, k6, p2.

Work the cable cross on rows 7, 13, 19, 25, 31, 37, and 43 of the body (counting from the setup row), then work plain cable rows between each cross.

The Seafarers Heart Motif (worked over 38 central stitches)

The heart is worked in reverse stockinette against a stockinette background, meaning the body of the heart is purled on right-side rows and knitted on wrong-side rows, while the background is knitted on right-side rows and purled on wrong-side rows. This causes the heart to “pop” forward in relief.

The heart motif begins at row 11 of the body and spans 26 rows. All rows not included in the heart chart are worked as plain stockinette (k on RS, p on WS) across the full 38 central stitches.

Reading the Chart Instructions:

In the chart below, each row describes what to do across all 38 central stitches on RS rows. WS rows are simply purled all the way across the 38 sts (except for the heart stitches themselves, which are knitted on WS rows to maintain the reverse stockinette texture).

For WS rows: purl all background stitches, knit all heart stitches.

RS Row 11 (begin heart): K17, p1, p1, p1, k1, p1, p1, p1, k17.
Heart sts: positions 18, 19, 20 and 21 (gap), 22, 23, 24. (Two “lobes” of the heart top begin here.)

RS Row 13: K15, p2, k1, p2, k2, p2, k1, p2, k15.

RS Row 15: K14, p3, k1, p3, k2, p3, k1, p3, k14.
The two lobes are now clearly defined.

RS Row 17: K13, p4, k1, p4, k2, p4, k1, p4, k13.

RS Row 19: K13, p4, k1, p4, k2, p4, k1, p4, k13. (Hold the lobe width steady.)

RS Row 21: K13, p4, k2, p4, k2, p4, k2, p4, k13.
(Close the gap between the two lobes — the top center of the heart fills in.)

RS Row 23: K13, p18, k13.
(The two lobes are now merged into one continuous band of reverse stockinette — this is the widest row of the heart.)

RS Row 25: K14, p16, k14.

RS Row 27: K15, p14, k15.

RS Row 29: K16, p12, k16.

RS Row 31: K17, p10, k17.

RS Row 33: K18, p8, k18.

RS Row 35: K20, p6, k20.

RS Row 37: K21, p4, k21.
(The heart narrows toward the bottom point.)

RS Row 38 (WS): P21, k4, p21.
(This WS row is noted separately because it is the last full-width row of the point before the final two decrease rows.)

RS Row 39: K22, p2, k22. (You can work this as k22, p2tog, k22 if you want a sharp single stitch point, which gives the most defined heart tip.)

RS Row 41: K38 (plain stockinette — the heart point has closed).

The heart motif is complete after row 41. Continue the body in plain stockinette for the central 38 stitches, maintaining the cable panels and seed stitch columns as established.

Completing the Body

Continue working in pattern as established — cables, seed stitch separators and borders, plain stockinette central panel — until the work measures approximately 15 inches from the cast-on edge, ending on a WS row.

Seed Stitch Border (Top Edge)

Rows 1–6: K1, p1; rep from to end of row.

BO all stitches in pattern (knit the knit stitches, purl the purl stitches as you bind off) for an edge that matches the cast-on end.

Knitting the Back Panel

The back panel can be worked one of two ways. For a fully reversible, seamless look, work an identical front panel. For a simpler finish, cast on 74 stitches and work the entire panel in seed stitch or a 2×2 rib, which gives a subtly textured back that lies flat and looks intentional.

If you are adding button closure, work the back in two pieces — each covering half the pillow height — with a button band worked along the opening edge of each piece.

Finishing and Assembly

Weave in all ends using your tapestry needle before seaming. Block both panels by wetting them thoroughly, pressing out the excess moisture between towels (do not wring), then pinning them to measurements on a flat, foam blocking mat. Let dry completely — ideally 24 hours. Blocking is non-negotiable for this project. It opens up the cable stitches, evens out the heart texture, and gives the whole piece a polished, professional appearance.

With RS facing out, hold the two panels together and seam three sides using mattress stitch. Mattress stitch creates an almost invisible seam along the side edges and works perfectly on the seed stitch borders at top and bottom. Insert your pillow form, then seam the remaining side. If using buttons, sew button loops or a buttonhole band on the inner piece, attach buttons to the outer piece, and fasten before inserting your pillow form.

Yarn Substitution Ideas

The pattern works with any worsted weight yarn. A smooth, plied yarn with good stitch definition — such as a wool-acrylic blend, 100% merino wool, or a cotton-linen blend for a summery coastal version — will show off the cables and heart texture most clearly. Avoid highly textured, fuzzy, or bouclé yarns for this pattern, as they obscure the stitch detail that makes the design worth knitting.

For a deeply nautical palette, try the pillow in a classic navy with cream for the heart worked in a contrasting strand. For a cottagecore or farmhouse look, a warm taupe or soft sage reads beautifully.

Tips for Success

Take your time with the heart rows. Counting carefully across the 38 central stitches before beginning each heart row prevents errors that are difficult to spot until several rows later. A row counter is helpful, as is marking your chart rows with a highlighter or sticky note as you complete them.

If a cable cross is giving you trouble, try working it more loosely — cables that feel tight usually just need a slightly looser yarn tension on the cross rows. Wooden or bamboo cable needles grip yarn better than metal ones if stitches keep sliding off.

Do not skip blocking. It genuinely transforms the finished object.

Display and Gift Ideas

The Seafarers Heart Knitted Pillow looks wonderful grouped with other coastal-themed cushions in navy and white stripes, but it also stands alone as a focal point on a bed, reading chair, or window bench. Because the heart motif is romantic without being overtly sentimental, this pillow crosses the line between Valentine’s Day gift and year-round home accessory without any awkwardness.

It makes a wonderful handmade wedding gift, a thoughtful housewarming present for someone moving to a coastal home, or a meaningful gift for a sailor, fisherman, or anyone with a love of the sea. Pair it with a handwritten note about the seafarers heart tradition, and you have given something that carries a story as well as warmth.

If you knit this pattern, take a photo and share it — there is nothing more encouraging for the knitting community than seeing the same design interpreted through different yarn choices and different hands. Happy knitting, and may every stitch bring you a little closer to the sea.
