Easy Knit Blanket Pattern: Seed Stitch Moss Stitch Throw

A Cosy Make for Every Level of Knitter

There is something deeply satisfying about knitting a blanket. It is one of those projects that earns its place on the needles — weighty enough to feel like a proper undertaking, yet simple enough to pick up and put down between life’s interruptions. This seed stitch moss stitch throw is exactly that kind of project. It asks very little of you in terms of technique, yet delivers something genuinely beautiful: a textured, reversible fabric with a handmade quality that no machine-made blanket can replicate.

Whether you are a complete beginner looking for your first substantial project, or a more experienced knitter who wants something meditative to work on while watching television, this pattern is for you. It uses just two stitches — knit and purl — alternated in a simple sequence that creates the wonderfully nubby texture you have probably admired on throws in interiors magazines and homeware shops. The best part? Once you have learned the rhythm of the stitch, you will barely need to look at the pattern at all.

In this post, we will walk you through everything you need to know about the pattern, including the yarn and needle recommendations, how seed stitch and moss stitch differ (and why it matters for your finished fabric), how to read the PDF download, and plenty of tips for getting the best possible result. By the end, you will feel completely confident casting on.

What Is Seed Stitch and What Is Moss Stitch?

Before we get into the pattern itself, it is worth clearing up a question that confuses a lot of knitters, particularly those who knit across both British and American patterns.

Seed stitch and moss stitch are names that are used somewhat interchangeably, but they can refer to slightly different stitch patterns depending on which tradition you are following.

In American knitting terminology, seed stitch is worked by alternating knit and purl stitches across every row. You cast on an odd number of stitches, knit one, purl one, and repeat to the end, finishing with a knit stitch. On the following row, you do exactly the same thing. Because the stitch pattern is offset from row to row, the knit stitches sit on top of purls and the purls sit on top of knits, creating the characteristic pebbly, textured surface.

In British knitting terminology, what Americans call seed stitch is often called moss stitch. However, British moss stitch can also refer to a double moss stitch, where the pattern is worked over two rows before the sequence shifts. This creates a slightly more elongated texture that some knitters find even more appealing than the classic version.

For this throw pattern, we use the single seed stitch or single moss stitch method — two rows of k1, p1, with the sequence shifting on the second row so that purls stack on knits and knits stack on purls. This is the most intuitive version to learn, and it creates a beautifully even, reversible fabric. You will hear both names used throughout this post because the pattern is designed for knitters on both sides of the Atlantic.

Why a Seed Stitch Throw Is the Perfect Project

Knitters often ask what to make after they have mastered the basics of casting on, knitting, and purling. The honest answer is that a seed stitch blanket ticks every box for a progression project.

It introduces you to working knit and purl stitches in the same row, which is the foundation of almost every other stitch pattern you will ever encounter. It is slow enough to give you plenty of practice, but varied enough that you will not get bored the way you might with miles of plain stocking stitch. And because the texture is created entirely by the arrangement of knit and purl stitches, there is nothing to count beyond a simple two-stitch repeat. No cables. No yarn overs. No slipped stitches or tricky decreases. Just knit and purl, knit and purl, row after row, until you have a thick and gorgeous throw to pile on the sofa.

There is also something to be said for the meditative quality of this kind of knitting. Once the rhythm is in your hands, your mind can wander. You can have a conversation, listen to a podcast, or follow along with a film without losing your place. The stitch pattern is forgiving — if you slip into the wrong rhythm for a row or two, the overall texture absorbs small inconsistencies in a way that a lace pattern or a colourwork design simply cannot.

From a practical standpoint, a seed stitch throw also has excellent drape and body. The alternating stitches create a fabric that does not curl at the edges the way plain stocking stitch does, which means you do not need to add a border. The blanket lies flat from the very first row. This is a significant advantage for a beginner, because it removes the need to plan for a finishing edge treatment and means the finished object looks polished and professional without any extra work.

Materials You Will Need

The pattern PDF includes full materials guidance, but here is an overview of what to gather before you begin.

Yarn: This throw works beautifully in any chunky or super-chunky weight yarn. A merino or merino-blend yarn will give you softness and a natural elasticity that makes the stitch definition really pop. Pure wool has wonderful warmth and structure, though an acrylic blend is more practical for a blanket that will need regular washing. If you want a cloud-like, extra-cosy result, a roving-weight yarn or a single-ply chunky gives the stitch pattern a slightly more relaxed look that suits the casual, home-comfort nature of a throw. The pattern specifies yardage requirements based on the finished dimensions, so check the label on your chosen yarn to calculate how many balls you will need.

Needles: Chunky blankets like this work up fastest on large needles, typically somewhere between 9mm and 12mm depending on your yarn weight and your personal tension. The pattern PDF includes a tension square guide, and it is worth spending twenty minutes knitting one before you begin. A blanket worked at a tighter tension than the pattern assumes will come out smaller and stiffer; worked too loosely, it may feel a little floppy. Ten minutes of swatching saves a lot of disappointment later.

Circular needles are strongly recommended, even though you will knit back and forth in rows rather than in the round. A large blanket on straight needles becomes heavy and unwieldy, and the weight pulling on your wrists can make the knitting feel like hard work. A long circular needle — 80cm or 100cm — allows the stitches to sit comfortably along the cable, and the whole thing rests in your lap rather than hanging off one needle.

Other tools: A tapestry needle for weaving in ends, stitch markers if you find them helpful for counting large numbers of stitches, and a row counter if you want to track your progress.

Reading and Using the PDF Download

The pattern is available as a PDF download from the Etsy UK shop, which means you can have it on your screen or printed out within moments of purchase. Here are a few notes on making the most of it.

The PDF is formatted for easy reading, with clear section headings, a materials list, abbreviation key, and written row-by-row instructions. There is no charted version — this pattern does not require one, because the stitch repeat is simple enough to follow from written instructions alone. Many knitters find that they memorise the sequence after just the first few rows and refer back to the PDF only to check their stitch count.

The pattern is written in UK terminology, with notes for US knitters where relevant. Any terminology that differs between the two traditions is clearly flagged. If you have knitted from both UK and US patterns before, you will be well used to navigating small differences; if this is your first time, the PDF includes a brief guide to the key terms.

There is also a section on tension and sizing, with guidance on how to adjust the blanket dimensions if you want to make a lap blanket, a cot blanket, a double-bed throw, or a wider sofa blanket. Because the stitch pattern is a simple two-stitch repeat, sizing up or down is very straightforward — you simply cast on more or fewer stitches (always an odd number) and adjust your yardage accordingly.

Step-by-Step: Getting Started

Cast on an odd number of stitches. For a standard lap throw, the pattern calls for a cast-on in the range of 61 to 81 stitches, depending on your yarn weight and desired width. For a larger sofa throw, you might cast on 101 or more. The PDF includes recommended cast-on counts for several finished sizes.

The long-tail cast on is recommended, as it creates a neat, slightly elastic edge that sits well with the seed stitch fabric. If you are not familiar with the long-tail cast on, the PDF includes a brief description, and there are many excellent video tutorials available online. A simple knitted cast on also works perfectly well.

Row 1: Knit 1, purl 1; repeat from to the last stitch, knit 1.
Row 2: Purl 1, knit 1; repeat from to the last stitch, purl 1.

These two rows form the complete pattern. Repeat them until the blanket reaches your desired length, then cast off in pattern. Weave in your ends and you are done.

It really is that simple. The genius of seed stitch is that those two rows, repeated faithfully, produce the richly textured fabric that makes this throw so appealing. There are no complicated pattern repeats to memorise, no increases or decreases, no counting beyond the initial cast-on.

Tips for a Beautiful Finish

Maintain an even tension. Because seed stitch involves constantly alternating between knit and purl stitches, it can be easy to let your tension slip slightly when you move the yarn to the front or back of the work. Take a moment to make sure the yarn is in the correct position before each stitch — yarn to the front before a purl, yarn to the back before a knit — and try to keep your yarn wrap consistent throughout.

Count your stitches regularly. Dropped stitches or accidental yarn overs can change your stitch count, and because this pattern depends on having an odd number of stitches, any change will throw off the alignment of the texture. Counting every ten or twenty rows takes a moment but saves you from unravelling a significant amount of work later.

Use stitch markers to divide large cast-ons. If you are making a large throw with 100 or more stitches, placing a marker every 20 stitches makes it easier to spot any counting errors quickly.

Block your finished blanket. Wet blocking — soaking the finished blanket in cool water, gently squeezing out excess moisture, and laying it flat to dry — evens out any inconsistencies in your tension and opens up the stitch texture beautifully. It also helps the blanket relax to its full dimensions. Most pure wool and wool-blend yarns benefit enormously from blocking; acrylics less so, but a light steaming can help.

Weave in ends securely. A blanket takes wear and washing over time, so it is worth taking extra care with your ends. Weave each one in for at least several centimetres, ideally in two different directions, to prevent them from working loose.

Yarn Suggestions and Colour Ideas

One of the great pleasures of knitting a seed stitch throw is choosing your yarn colour. Because the texture does all the visual work, a single solid or semi-solid colour shows off the stitch pattern to its absolute best. Heather tones — oatmeal, stone, warm grey, dusty rose, soft sage — look particularly beautiful in this stitch because the slight variation in the yarn catches the light differently in the raised and recessed parts of the fabric.

If you prefer something bolder, a deep jewel colour in the same simple palette — rich teal, forest green, burnt terracotta, navy — gives the throw a more dramatic presence. Because the stitch pattern is so classic and understated, it carries bold colour with ease.

Variegated or hand-dyed yarns can look lovely too, though very busy colourways can sometimes compete with the texture rather than complement it. If you love variegated yarn, look for one with a gentle tonal shift rather than high-contrast colour changes.

For a luxurious feel, merino, alpaca, or a merino-alpaca blend is hard to beat. Merino is wonderfully soft against bare skin and has a natural bounce that keeps the stitch definition crisp. Alpaca adds incredible warmth and a soft halo that gives the blanket a slightly dreamy quality. For practicality and easy care, a good quality acrylic or acrylic-merino blend is a sensible choice for a blanket that will be used and washed regularly.

Making This Pattern Your Own

While the pattern is written as a straightforward seed stitch throw, there are several small ways to personalise your make if you want to experiment.

You could work a border of plain garter stitch — knitting every row — around the edge of the blanket for a slightly different frame. Because garter stitch also lies flat, it is easy to integrate and adds a subtle visual contrast. Simply knit the first and last few stitches of every row and work a handful of garter rows at the beginning and end of the blanket.

You could also use the same pattern with a chunkier or thinner yarn to change the scale of the texture. The same k1, p1 structure worked in a finer aran-weight yarn creates a more delicate, lightweight fabric that works beautifully as a decorative throw rather than a warm winter blanket. Worked in a roving-weight yarn on extra-large needles, it becomes a dramatic, oversized statement piece.

Stripe variations are another option. Working sections of seed stitch in alternating colours creates a striped throw with a difference — the texture remains the same throughout, but the colour changes add visual interest without adding complexity.
