Splendid Andromeda Knitted Pillow — Free Knitting Pattern

There is something almost magical about transforming a skein of yarn into something you can actually rest your head on. The Andromeda Knitted Pillow is one of those projects that looks far more complicated than it actually is — a celestial swirl of texture and color that brings a little galaxy-inspired wonder right into your living room. Whether you are a seasoned knitter looking for your next satisfying weekend project or an adventurous beginner ready to stretch your skills, this pattern is designed to guide you every step of the way.

This free knitting pattern produces a finished pillow approximately 18 inches square, featuring a stunning combination of twisted stitches, yarn-over lace panels, and a subtle color gradient that evokes the spiral arms of the Andromeda galaxy. The result is a decorative pillow that looks like it belongs on the pages of a high-end home décor magazine — but costs a fraction of what you would pay for something similar in a boutique.

Let’s get into everything you need to know before you cast on your first stitch.

About This Pattern

The Andromeda Knitted Pillow takes its name and its spirit from the nearest major galaxy to our own Milky Way. Just as Andromeda is a swirl of billions of stars caught in a slow celestial dance, this pillow features a radiating panel design worked from the center outward on each side, with a series of cable twists and eyelet rows that mimic the sense of movement and light you might see through a telescope on a clear night.

The pattern is written for a flat knit, seamed construction, meaning you will knit two separate squares and join them together around a pillow insert. This method makes the pattern accessible to knitters who may not be comfortable with working in the round, and it also makes it easy to wash the cover separately from the insert. The back of the pillow uses a simple seed stitch for a classic, clean look that lets the front panel do all the talking.

Skill level: Intermediate. You should be comfortable with basic knit and purl stitches, simple cable techniques (no cable needle required for most of this pattern), and yarn-overs before beginning. If you are newer to cables, a short practice swatch is recommended, but do not let the intermediate label discourage you — this pattern is written with clear, row-by-row instructions that will walk you through every twist and turn.

Materials You Will Need

Yarn: Approximately 350–400 yards of a worsted weight (weight 4) yarn in your main color (MC), and 80–100 yards of a coordinating color (CC) for accent rows. The original sample was knitted in a deep plum heather (MC) with a soft dusty rose (CC), but this pattern looks equally stunning in navy and gold, charcoal and cream, or any pairing that speaks to you. A wool or wool-blend yarn is recommended for its elasticity and stitch definition, though a good acrylic will work beautifully as well if you prefer an easy-care option.

Needles: US size 7 (4.5mm) straight or circular needles. If you tend to knit tightly, go up to a US 8. If you tend to knit loosely, try a US 6. Always swatch before committing to a needle size.

Notions: Stitch markers (4), a tapestry needle for seaming and weaving in ends, scissors, and an 18-inch square pillow insert. A cable needle is optional — the cable crossings in this pattern are simple two-stitch twists that most knitters find easy to work without one, but keep one handy in your project bag if you prefer.

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch on US 7 needles after blocking.

Please take the time to knit a gauge swatch. Because this is a pillow and not a fitted garment, the stakes for being slightly off are lower, but if your gauge is significantly looser or tighter than specified, your finished pillow front may not align properly with the back panel, and the overall dimensions will be off. Block your swatch the same way you intend to block the finished pieces — if you are using a wool or wool blend, a wet block will relax the fabric and give you a truer reading.

Abbreviations

Throughout this pattern, the following abbreviations are used. K stands for knit, P stands for purl, YO stands for yarn over, K2tog stands for knit two stitches together, SSK stands for slip, slip, knit (a left-leaning decrease), T2R stands for twist 2 right (knit into the second stitch on the left needle, then knit the first stitch, slip both off together), T2L stands for twist 2 left (with right needle behind left, knit the second stitch through the back loop, then knit the first stitch normally, slip both off), SM stands for slip marker, PM stands for place marker, and RS and WS stand for right side and wrong side respectively.

Pattern Notes

The front panel is worked flat in rows. Markers are placed to divide the panel into five sections: two seed stitch border columns on each side, and three pattern sections across the center. The main Andromeda motif runs down the center column, flanked by smaller lace and twist panels on either side.

The accent color (CC) is used only for two-row stripes at regular intervals. These stripes are worked in reverse stockinette on the right side (meaning you purl across on the RS row when working in CC), which creates a subtle ridge effect that adds dimension to the finished fabric. You do not need to cut the yarn between color changes; simply carry the unused color loosely up the side of the work.

All cable twists in this pattern are worked on right side rows only. Wrong side rows are worked as they appear — knit the knit stitches and purl the purl stitches, unless otherwise indicated.

Front Panel Instructions

Cast on 92 stitches using MC and a long-tail cast on, which produces a neat, stable foundation edge that complements the overall look of the finished piece.

Begin with the border setup. Row 1 (RS): Work K1, P1 across the first 4 stitches for seed stitch border, PM, work the next 84 stitches according to the chart or written instructions below, PM, work the final 4 stitches in K1, P1 seed stitch. Row 2 (WS): Work the 4 border stitches in seed stitch, SM, work across the center 84 stitches, SM, work the final 4 border stitches in seed stitch.

The center 84 stitches are divided as follows: 12 stitches of lace panel A, PM, 60 stitches of the central Andromeda cable and lace motif, PM, 12 stitches of lace panel A (mirrored).

Lace Panel A (worked over 12 stitches, 8-row repeat):

Rows 1 and 5 (RS): P2, K2, YO, SSK, K2, YO, SSK, P2.
Rows 2, 4, 6, 8 (WS): K2, P8, K2.
Row 3 (RS): P2, K1, YO, SSK, K2, K2tog, YO, K1, P2.
Row 7 (RS): P2, YO, SSK, K4, K2tog, YO, P2.

Repeat these 8 rows for the full length of the panel.

Central Andromeda Motif (worked over 60 stitches, 16-row repeat):

The heart of this design is a radiating spiral effect created by combining cable twists that travel outward from the center with yarn-over lace that fills the negative space between them. Think of it as the arms of a galaxy spinning slowly outward.

Row 1 (RS): P5, T2R, K4, YO, K2tog, P6, T2R, T2L, P6, SSK, YO, K4, T2L, P5.
Row 2 and all even WS rows: Work all stitches as they appear — knit the purls and purl the knits, maintaining the established rib and stockinette columns.
Row 3 (RS): P4, T2R, K4, YO, K1, K2tog, P5, T2R, K2, T2L, P5, SSK, K1, YO, K4, T2L, P4.
Row 5 (RS): P3, T2R, K4, YO, K2, K2tog, P4, T2R, K4, T2L, P4, SSK, K2, YO, K4, T2L, P3.
Row 7 (RS): P3, K6, YO, K3, K2tog, P3, T2R, K6, T2L, P3, SSK, K3, YO, K6, P3.
Row 9 (RS): P3, T2L, K4, SSK, YO, K2, P4, T2L, K4, T2R, P4, K2, YO, K2tog, K4, T2R, P3.
Row 11 (RS): P4, T2L, K4, SSK, K1, YO, P5, T2L, K2, T2R, P5, YO, K1, K2tog, K4, T2R, P4.
Row 13 (RS): P5, T2L, K4, SSK, YO, P6, T2L, T2R, P6, YO, K2tog, K4, T2R, P5.
Row 15 (RS): P5, K6, P8, K2, YO, SSK, K2, P8, K6, P5.

Repeat these 16 rows for the full length of the panel.

Color Stripe Rows:

Every 24 rows, work 2 rows in CC as follows. Drop MC (do not cut). Join CC. CC Row 1 (RS): Purl across all stitches (including border). CC Row 2 (WS): Knit across all stitches. Drop CC, pick up MC, and continue in pattern. These reverse stockinette ridges appear in your chosen accent color and create the soft glow effect across the surface of the pillow.

Continue working in pattern, introducing CC stripes every 24 rows, until the front panel measures approximately 18 inches from the cast-on edge, ending after a complete 16-row repeat of the Andromeda motif. Bind off all stitches in pattern using MC.

Back Panel Instructions

The back of the pillow is worked in a simple but beautiful all-over seed stitch, which adds texture without competing with the front panel’s elaborate design. It also has a practical advantage — seed stitch lies flat naturally, so there is no need to worry about curling edges.

Cast on 92 stitches using MC.

Row 1: K1, P1; repeat from to end.
Row 2: P1, K1; repeat from to end.

Repeat these two rows until the back panel measures the same length as the front panel. Bind off in seed stitch.

Finishing

Weave in all ends on both panels using your tapestry needle, being careful to secure the yarn tails from the CC stripe rows neatly on the wrong side of the front panel. If you are using a wool or wool-blend yarn, wet block both panels before seaming. Pin them to your desired dimensions (18 inches square) on a foam blocking mat, mist generously with water, and allow to dry completely. Blocking will open up the lace sections of the Andromeda motif beautifully and even out any slight tension irregularities in the cable panel.

Once both pieces are dry and flat, hold them with wrong sides together and use a mattress stitch seam along three sides, working through both layers along the outermost edge of the seed stitch border. Insert your pillow form, then close the fourth side with mattress stitch. Alternatively, if you would like to be able to remove the cover for washing, you can work three sides as above and add a row of evenly spaced snaps, hook-and-eye closures, or a simple lapped button band along the fourth edge.

Sizing and Customization Notes

This pattern is written for an 18-inch pillow insert, but it adapts beautifully to other sizes. For a 20-inch pillow, cast on 102 stitches and add an additional 10 rows to the total length. For a 16-inch pillow, cast on 82 stitches and reduce the length accordingly. The Andromeda motif and lace panels are self-contained enough that they scale well with modest adjustments to the surrounding background sections.

If you want to skip the color stripes and work the entire pillow in a single color, simply continue in MC throughout. The result is quieter but no less sophisticated — in a deep, rich solid color like forest green or burgundy, the cable and lace texture becomes the undisputed star of the show. On the other hand, if you love color, you could introduce a third or even fourth accent color for the stripes to create a more playful, gradient effect.

For a chunkier, quicker version, try scaling up to a bulky weight yarn and US 10 needles, adding a stitch to each repeat to accommodate the increased gauge. The finished texture will be bolder and more graphic.

Care Instructions

If you chose a wool or wool-blend yarn, hand wash the pillow cover gently in cool water with a wool wash product, press out excess water without wringing, and dry flat. For acrylic yarns, most can be machine washed on a gentle cycle and dried on low — check the yarn label to confirm. Pillow covers benefit from occasional reshaping while still damp to keep the lace and cable sections looking their best.

A Few Words on the Joy of This Project

There is a rhythm that develops when you knit a project like this one. The first repeat of the Andromeda motif feels like learning a new language — you are looking at your hands, checking the pattern, placing the twists carefully. By the second or third repeat, something shifts. Your fingers start to remember where they are going. The pattern becomes less like a series of instructions and more like a melody you can almost hear.

That is the gift of a well-designed repeat pattern. It gives your hands something interesting to do while your mind wanders wherever it needs to go. Some of the best knitters I know describe their craft as a form of active meditation, and projects like this one — just complex enough to hold your attention, just repetitive enough to find a groove — are exactly the kind of work that puts you in that state.

When you hold the finished pillow in your hands for the first time and see the spiral arms of the Andromeda motif swirling outward from the center, framed by the soft ridges of the accent color stripes, you will understand why this pattern has that name. There is something cosmic about the satisfaction of making something beautiful out of nothing but string and two sticks. The universe, after all, is not so different.
