Free Knitting Pattern: Seaside Sunset Blanket

There is something deeply satisfying about sitting down with a pair of needles, a ball of yarn, and a project that feels like it was made for long evenings and slow mornings. The Seaside Sunset Blanket is exactly that kind of project. Inspired by the warm, layered colors of a coastal sunset — think deep coral bleeding into soft peach, dusty rose meeting golden amber, and the faintest blush of lavender as the sky gives way to night — this blanket brings the feeling of the shore right into your living room, even if the nearest ocean is a thousand miles away.

Whether you are a seasoned knitter looking for a satisfying weekend project or someone who has recently graduated past scarves and dishcloths and is ready to try something more expansive, this pattern is designed to grow with you. The stitch work is accessible, the construction is straightforward, and the result is a blanket that looks far more complicated than it actually is. People will ask you where you bought it, and you will get to say you made it yourself.

Let’s get into everything you need to know.

About This Pattern

The Seaside Sunset Blanket is worked flat, from bottom to top, in a combination of stockinette and a simple textured stripe sequence that creates the look of layered color without requiring any complex colorwork techniques. Each color section is its own gentle wave of tone, and when you lay the finished blanket out, the transitions feel effortless and painterly.

The finished blanket measures approximately 48 inches wide by 60 inches long, making it a generous lap blanket or a cozy throw for the back of a sofa. You can adjust the width by adding or subtracting stitches in multiples of four, and you can adjust the length simply by adding or removing color stripe repeats.

This pattern is written for knitters with at least some experience casting on, working basic stitches, and changing yarn colors. If you have completed a few smaller projects and are comfortable with the basics, you are ready for this one.

Materials You Will Need

Yarn: You will need a worsted weight yarn in five colors. For the traditional Seaside Sunset colorway, look for shades that read as a sunset gradient. The quantities listed below are approximate for the standard size.

• Color A (deep coral or terracotta): approximately 300 yards
• Color B (warm peach or apricot): approximately 280 yards
• Color C (soft dusty rose): approximately 280 yards
• Color D (golden amber or honey): approximately 260 yards
• Color E (pale lavender or blush): approximately 240 yards

Any worsted weight yarn with good stitch definition will work beautifully here. Wool and wool blends give the most structure and warmth, and they block wonderfully if you want a polished finish. Cotton or cotton blends are a great choice if you want something lighter and more breathable for warmer climates. A good acrylic will also work well if you want something machine washable, which is especially practical if the blanket is going to be used regularly on the couch or given as a gift to someone with a busy household.

Needles: US size 8 (5.0 mm) straight or circular needles, at least 32 inches long. Circular needles are recommended for a project this wide simply because they can hold more stitches comfortably, but you are working flat, so you will not be joining in the round.

Other supplies:

• Tapestry needle for weaving in ends
• Scissors
• Stitch markers (optional, but helpful for keeping track of pattern repeats)
• Measuring tape

Gauge

18 stitches and 24 rows = 4 inches in stockinette stitch on US size 8 needles.

Please take the time to knit a gauge swatch before you begin the blanket. Gauge swatches feel like an inconvenience, but they are genuinely the difference between a blanket that comes out the size you intended and one that ends up as either a doll blanket or a bed covering. If your swatch has more stitches per inch than the gauge listed, try going up a needle size. If you have fewer stitches per inch, go down a needle size. A little adjustment at the start saves a lot of heartache at the end.

Abbreviations

Throughout this pattern, the following abbreviations are used:

• CO — cast on
• BO — bind off
• k — knit
• p — purl
• RS — right side
• WS — wrong side
• rep — repeat
• st(s) — stitch(es)
• sl — slip

Pattern Notes

Color changes: When changing colors, always do so at the beginning of a right side row. Cut the old yarn, leaving a tail of about six inches for weaving in. Join the new color by leaving a similar tail and beginning to knit. You do not need to carry yarn up the side on this project, as the color sections are long enough that cutting and rejoining is cleaner and less bulky.

Edge stitches: The pattern uses a simple slipped stitch edge on both sides of the blanket. On every row, slip the first stitch purlwise with the yarn in front, then bring the yarn to the back before working the second stitch. This creates a clean, chained edge along both sides that makes the blanket look tidy and professional without any additional finishing.

Reading the pattern: Right side rows are odd-numbered rows. Wrong side rows are even-numbered rows.

The Pattern

Cast On

Using Color A and your US size 8 needles, cast on 216 stitches. If you are adjusting the size, remember that your stitch count should be a multiple of 4, plus an additional 4 stitches for the edge stitches on each side (2 stitches per side).

Before you begin working, take a moment to count your stitches twice. Starting with the correct count is much easier than trying to troubleshoot a stitch count problem twenty rows in.

Section One: Deep Coral (Color A)

Color A forms the foundation of the blanket and represents the deepest, richest tones of the sunset horizon.

Setup Row (WS): Sl 1 purlwise wyf, p to last st, sl 1 purlwise wyf. Turn.

Row 1 (RS): Sl 1 purlwise wyf, bring yarn to back, k to last st, sl 1 purlwise wyf. Turn.

Row 2 (WS): Sl 1 purlwise wyf, p to last st, sl 1 purlwise wyf. Turn.

Repeat Rows 1 and 2 until Color A section measures 6 inches from the cast on edge, ending with a WS row. This will be approximately 36 rows, but trust your measuring tape over your row count.

Transition Stripe (Color A and Color B)

Before moving fully into Color B, you will work a short transition stripe that blends the two colors and softens the shift between sections. This is the detail that makes the blanket feel like a real sunset gradient rather than simple color blocking.

With Color B:

Row 1 (RS): Sl 1, k to last st, sl 1.
Row 2 (WS): Sl 1, p to last st, sl 1.
Row 3 (RS): Sl 1, k2 with Color A, k2 with Color B, rep from to last st, sl 1.

For Row 3, you will need to carry both yarns loosely across the row. This is the only row in the pattern that asks you to work with two colors at once. Keep your tension relaxed and do not pull the floats too tight. If you are not comfortable with carrying two yarns, you can substitute this row with a simple knit row in Color B and the effect will still be beautiful.

Row 4 (WS): Sl 1, p to last st, sl 1 using Color B only.

Section Two: Warm Peach (Color B)

Cut Color A. Continue with Color B only.

Repeat Rows 1 and 2 from Section One (the basic stockinette with slipped edge stitches) until Color B section measures 5.5 inches, ending with a WS row.

Textured Stripe

After each full color section, you will work a four-row textured stripe before the transition into the next color. This adds a subtle ridge of texture that catches the light differently than the stockinette sections and gives the blanket a sense of visual movement.

Row 1 (RS): Sl 1, k4, p4, rep from to last st, sl 1.
Row 2 (WS): Sl 1, work stitches as they appear (k the k sts, p the p sts) to last st, sl 1.
Row 3 (RS): Sl 1, p4, k4, rep from to last st, sl 1.
Row 4 (WS): Sl 1, work stitches as they appear to last st, sl 1.

Work the transition stripe as described in the previous transition section, substituting Color C for Color B in the final two rows.

Section Three: Dusty Rose (Color C)

Cut Color B. Continue with Color C only.

Repeat the basic stockinette pattern (Rows 1 and 2, with slipped edge stitches) until Color C section measures 5.5 inches, ending with a WS row.

Work the four-row textured stripe.

Work the transition stripe, substituting Color D for Color C in the final two rows.

Section Four: Golden Amber (Color D)

Cut Color C. Continue with Color D only.

Repeat the basic stockinette pattern until Color D section measures 5.5 inches, ending with a WS row.

Work the four-row textured stripe.

Work the transition stripe, substituting Color E for Color D in the final two rows.

Section Five: Pale Lavender (Color E)

Cut Color D. Continue with Color E only.

Repeat the basic stockinette pattern until Color E section measures 6 inches, ending with a WS row.

Color E mirrors Color A in length, giving the blanket a satisfying symmetry — the sunset beginning and ending with its most deeply saturated tones bookending the softer middle colors.

Continue the Gradient

At this point you have completed one full gradient sequence from deep coral to pale lavender. The blanket in the standard length repeats this sequence once more in reverse, working from Color E back toward Color A, before finishing with a final Color A section. This reverse gradient creates the effect of a full sunset cycle and gives the blanket a natural, complete feeling.

Work the textured stripe in Color E, then begin the transition stripe in reverse, moving back toward Color D.

Repeat all sections in reverse order: Color D (5.5 inches), textured stripe, transition, Color C (5.5 inches), textured stripe, transition, Color B (5.5 inches), textured stripe, transition, and finally Color A for a final 6 inch section ending with a WS row.

Bind Off

Using Color A, bind off all stitches loosely on a RS row. A loose bind off is important for a blanket — a tight bind off edge will pucker and resist blocking. If you tend to bind off tightly, consider going up one needle size just for the bind off row.

Finishing

Once you have bound off, the finishing work is what takes your blanket from “knitted thing” to “beautiful handmade piece.”

Weave in all ends using your tapestry needle. Weave each tail in at least two directions for security, especially at the color change points where the yarn may experience a little more tension over time.

Blocking: Wet blocking will make a significant difference in the final appearance of this blanket. Submerge the finished blanket in cool water and allow it to soak for about 20 minutes until fully saturated. Gently squeeze out the excess water without wringing or twisting, then roll the blanket in a clean dry towel and press to remove more moisture. Lay the blanket flat on a blocking mat or clean surface, gently stretching it to the desired dimensions, and allow it to dry completely before moving it. This process evens out the stitches and opens up the texture in the stripe sections beautifully.

Yarn Substitution Ideas

The beauty of a project like this is that the color palette is entirely in your hands. Some wonderful alternative colorways to consider:

A stormy sea version works well in deep navy transitioning through steel blue, smoky grey, and soft white, evoking the kind of dramatic coastal sky that feels electric before a storm rolls in.

A desert sunrise version is stunning in terracotta moving through burnt orange, warm gold, sage green, and soft yellow — more earthy and southwestern, but equally evocative of open sky and wide landscapes.

A winter forest palette in deep pine, forest green, warm taupe, cream, and pale icy blue creates something that feels completely different in mood — quieter, colder, and beautifully wintery.

Tips for Success

The Seaside Sunset Blanket is a meditative project. Because the stitch pattern is simple and repetitive, you can often work on it while watching television, listening to a podcast, or sitting in good conversation. The real work is in the rhythm of it — the counting of inches, the small ceremony of cutting one color and joining the next, the gradual growth of something large and warm from something as humble as a skein of yarn and a pair of needles.

Keep your tension consistent throughout. If you find your tension shifting when you switch colors, take a few extra rows to settle into the new yarn before it becomes a noticeable difference in your fabric.

Take your time with the transition stripes. Those rows are where the blanket earns its gradient effect, and a little care there pays off in the final result.

If you are gifting this blanket, consider including a small card with the fiber content and care instructions. Handmade gifts deserve to be cared for properly, and the person receiving your work will appreciate knowing how to keep it beautiful for years to come.

A Note on Knitting and Making

Knitting has a long history as both a practical and an artistic craft, and there is something quietly countercultural about choosing to make something by hand in a world that prizes speed and convenience above almost everything else. Every stitch in this blanket represents a small act of patience. When it is finished and you wrap it around your shoulders or drape it over a guest who needs warming, you will feel that in a way that is hard to put into words.

The Seaside Sunset Blanket is a free pattern, and you are welcome to make as many as you like, to give them away, to sell finished objects made from this pattern, and to share it with any fellow knitters in your life who might love it. The only request is that if you share the pattern itself, you link back to the original so other knitters can find it easily.

Happy knitting. May your yarn never tangle and your tension always hold.
