Cat Blanket Knitting Pattern: Reversible Double Knit Baby & Throw

If you’ve ever curled up on the couch with a cat in your lap and a half-finished knitting project on the armrest, you already understand the particular joy of making something warm and handmade for the creature you love most. A cat blanket is one of those satisfying knitting projects that feels small enough to finish but meaningful enough to matter — and when it’s designed as a reversible double knit, it becomes something truly special. Whether you’re knitting for a new kitten, a senior rescue cat, or a beloved furry companion who has claimed every soft surface in your home, this pattern delivers a plush, two-sided blanket that works equally well as a baby lap blanket or a generous throw.

This guide walks you through everything you need to know about the cat blanket knitting pattern, from the materials and techniques involved to tips for customizing the size and making the most of the double knit construction. The pattern itself is available as a PDF download in English, so you can save it to your devices, print it at home, or pull it up on your tablet right next to your yarn basket.

Why Double Knit? The Magic of a Reversible Fabric

Double knitting is one of those techniques that feels like a secret handshake among experienced knitters. When you work it correctly, you’re essentially knitting two separate layers of fabric simultaneously on a single set of needles, with the two layers interlocked at the edges. The result is a blanket that has no wrong side. Both faces look identical — or, if you use contrasting colors, they display a mirror image of each other with the colors reversed.

For a cat blanket, this construction has some very practical advantages. Cats have no interest in which side of a blanket is the “right” side; they will flip it, paw it, knead it, and eventually arrange it to their own satisfaction regardless of what you intended. A reversible double knit means there’s never a wrong orientation. The blanket always looks neat and finished no matter how it lands.

Double knit fabric is also significantly warmer and denser than a single-layer stockinette or garter stitch piece of the same dimensions. You’re essentially getting two blankets in one, which means more insulation and a satisfying weight that cats tend to love. That heavier drape encourages them to stay put, which is exactly what you want from a dedicated cat blanket.

From an aesthetic standpoint, the two-color reversible design opens up a world of possibilities. You can choose coordinating neutrals for an understated, modern look, or go bold with high-contrast combinations that show off the pattern geometry beautifully. The cat silhouette or geometric motif (depending on the design variation you choose within this pattern) shows up in one color on one side and inverts to the second color on the back — a visual effect that always gets compliments.

About This Pattern: Baby Blanket and Throw Sizes

This pattern is written for two sizes: a baby blanket size and a full throw. The baby blanket is a perfect lap-sized piece that works well in a cat bed, in a carrier, on a pet stroller, or tucked into a cozy corner of a couch. The throw is generous enough to serve as a human lap blanket doubled over a sofa arm, giving your cat plenty of surface area to stretch out on.

The baby blanket measures approximately 14 by 18 inches after blocking, making it an ideal “pet blanket” size that fits neatly in most cat beds without bunching. The throw version comes in at roughly 28 by 36 inches, which is large enough for a multi-cat household or for a cat who insists on maximum territory.

Both sizes use the same stitch pattern and construction method, so once you understand how the double knit works, switching between them is simply a matter of casting on a different number of stitches and working more rows. The PDF download includes full instructions for both sizes with separate stitch counts, row counts, and yardage estimates clearly labeled, so there’s no risk of confusion between the two versions.

Materials You’ll Need

Before you cast on, gather your materials. Double knitting does require a bit more yarn than a standard single-layer blanket of the same dimensions, so it’s worth being intentional about your yarn choices before you begin.

Yarn: You’ll need two colors of yarn — referred to throughout the pattern as Color A and Color B. For the baby blanket size, plan on approximately 300 yards of each color in a worsted weight yarn. For the throw, you’ll want roughly 700 yards of each color. Choose a yarn that is machine washable if the blanket will get regular use from pets or children. A superwash merino or a durable acrylic-wool blend both work beautifully. Pure acrylic is a budget-friendly option that holds up extremely well to washing, which matters enormously for a cat blanket. Avoid anything too loosely spun or delicate, as cat claws and double knitting don’t play well with fragile fibers.

Needles: Use a US size 7 (4.5mm) circular or straight needle for worsted weight yarn, or adjust to match your gauge. Circular needles are recommended even for flat knitting because the cord gives you more room to manage the doubled stitch count comfortably.

Gauge: 18 stitches and 24 rows per 4 inches in double knit stockinette, measured after blocking. Gauge matters more in this pattern than in many others because the two layers need to stay properly aligned. Take the time to work a gauge swatch before committing to the full project.

Other supplies: Tapestry needle for weaving in ends, stitch markers to track pattern repeats, and scissors. If you are working the throw size, a row counter is helpful for keeping your place in longer sections.

Understanding the Double Knit Construction

If you are new to double knitting, the technique can look intimidating on paper but becomes intuitive surprisingly quickly. The basic principle is this: you work every row with both yarns in hand, alternating between a knit stitch in Color A and a purl stitch in Color B (or vice versa, depending on which face of the fabric you’re building). The knit stitches form one layer, and the purl stitches form the other. The yarn is always held in front for purls and in back for knits, and you must keep the two yarns untangled by consistently bringing them around in the same direction.

The cat motif in this pattern is worked using a color chart. On each row, you’ll follow the chart to determine which color goes to the front (knit position) and which goes to the back (purl position) for each stitch pair. When you switch the color that knits and the color that purls, you’re changing which side of the fabric shows a particular color — which is how the motif and its reverse-color mirror image are created simultaneously.

The pattern PDF includes a written-out row-by-row version of the instructions as well as a chart, so you can work in whichever format suits your learning style. Many knitters find they start with the written version and graduate to the chart once the rhythm of the stitch pattern becomes familiar.

One practical note: double knitting with two colors means you’ll always be working with both strands active. Some knitters hold one color in each hand, continental-style in the left and English-style in the right. Others use two yarn bobbins positioned on either side of their work. There’s no single correct method — find whatever keeps your yarn organized and tangle-free for you.

The Cat Motif: Design Details and Customization

The central design element in this pattern is a simplified cat silhouette worked in intarsia-style double knit color placement. The cat figure — with its distinctive pointed ears and curved tail — sits centered on the blanket, surrounded by a simple geometric border that echoes the lines of the main motif.

The motif is sized to work proportionally in both the baby and throw versions of the pattern. In the baby blanket, the cat figure spans approximately 7 inches in height, giving it a bold, graphic presence without overwhelming the piece. In the throw, the motif scales up naturally with the additional rows, filling the center field with satisfying confidence.

Because this is a double knit construction, the motif automatically appears on both sides of the blanket — but with the colors reversed. If you knit Color A as a warm cream and Color B as a deep charcoal, the front of the blanket will show a charcoal cat on a cream background, and the back will show a cream cat on a charcoal background. Both versions are equally beautiful, and honestly, this two-sided quality is one of the most rewarding aspects of the entire project.

Customization is genuinely easy with this pattern. The border sections are worked in a simple two-color check or stripe, which can be swapped out for solid color sections if you prefer a cleaner look. The cat motif itself can be omitted entirely to create a geometric double knit throw — the pattern includes instructions for this variation as well, making it usable for knitters who want a handsome blanket without the representational design.

Color choice is, of course, where you can really make the pattern your own. Consider your cat’s coloring and match accordingly: a rich tortoiseshell palette of burnt orange and deep brown for a calico cat, cool silver and white for a Russian Blue, or classic black and white for a tuxedo cat. Or forget realism entirely and go for your favorite color combination. A dusty sage green paired with mustard yellow makes for a stunning, contemporary color-blocked aesthetic that works as well in a modern apartment as it does in a cozy farmhouse living room.

Knitting the Blanket: A Step-by-Step Overview

The blanket is worked flat, from the bottom border upward, in one continuous piece. There are no seams to sew and no separate pieces to join, which makes the finishing process beautifully simple.

You begin with a cast-on edge that uses a two-color long-tail cast on to set up the alternating stitch pairs required for double knitting. The pattern walks you through this setup row carefully, since it’s the foundation for everything that follows. If you’ve never worked a two-color long-tail cast on before, the written instructions in the PDF provide a clear step-by-step breakdown.

The bottom border is worked in a two-color ribbed or garter-style double knit edge for approximately 8 rows, which gives the blanket a tidy, stable hem that lies flat after blocking. From there, you transition into the main body and begin following the chart for the cat motif.

The body section is the longest portion of the work, and it’s also where the rhythm of double knitting settles in and becomes meditative. Once you’ve internalized the knit-front, purl-back pattern and are tracking your color chart with ease, this portion of the blanket knits up steadily and satisfyingly. The throw version will take longer than the baby blanket, obviously, but many knitters find that the engaging two-color work keeps them from losing interest the way a plain stockinette throw sometimes can.

After the motif section is complete, you work the top border to match the bottom, then bind off using a two-color stretchy bind-off that keeps the edge consistent with the cast-on. The PDF includes detailed instructions for this finishing technique as well.

Finishing, Blocking, and Care

Once you’ve worked the final bind-off row, weave in your ends carefully on both layers. Double knitting produces more ends than single-layer knitting, since you’re cutting and joining two yarns simultaneously wherever the pattern requires it. Take your time with this step — a well-woven-in end is nearly invisible, while a sloppy one can unravel over time, especially on a blanket that sees regular use.

Blocking is highly recommended for this pattern. Wet blocking — soaking the finished blanket in cool water, gently pressing out the excess moisture in a towel, and then pinning or laying flat to dry — will even out the stitches, help the motif sit crisply, and allow the fabric to relax into its final dimensions. Double knit fabric can sometimes look uneven or puckered off the needles and transforms remarkably after blocking.

For ongoing care, follow the wash instructions for your chosen yarn. Most superwash wools and acrylic blends can be machine washed on a gentle cycle in cool water and laid flat to dry. Avoid high heat, which can cause wool to felt and acrylic to pill more rapidly. A blanket that is washed regularly and treated well will maintain its loft and color for years.

The PDF is formatted for easy reading on both screen and printed page, with the chart and written instructions clearly laid out on separate pages so you can print just what you need.

The PDF includes the full pattern for both the baby blanket and the throw, a materials list with yardage estimates, a gauge section with instructions for swatching, step-by-step instructions for the two-color long-tail cast on and the two-color bind-off, the cat motif chart with a color key, written row-by-row instructions for every section, notes for the no-motif geometric variation, and blocking and care recommendations.

The pattern is written for intermediate knitters who are comfortable with basic knit and purl stitches and color work, but who may be new to double knitting specifically. Every technique unique to this construction method is explained within the pattern itself, so you won’t need a separate reference book to complete the project.

A Few Final Tips Before You Cast On

Start with the baby blanket size if this is your first double knitting project. The smaller scale lets you get familiar with the technique and the chart without committing to a full throw’s worth of work. Many knitters make the baby blanket as a practice piece and then immediately cast on the throw, feeling confident and well-prepared.

Keep your tension relaxed. Double knitting can encourage tight knitters to grip harder because they’re managing two strands — resist this. A looser, more fluid tension produces a softer, more even fabric. If your stitches are difficult to work and the needles feel stiff, go up half a needle size.

Use stitch markers generously. Place them at the beginning of each border section and at each side of the central motif field. They’re easy to remove later and invaluable for staying oriented while you’re learning the pattern.

Most importantly, enjoy the process. Knitting a blanket for the cat who shares your home is one of those quietly generous acts that may go completely unnoticed by the recipient — until it doesn’t, and you find them curled up on it in a perfect circle, purring. That moment is worth every row.
