8 Knitted Rainbow Blanket Patterns | The Knit Crew

There is something undeniably joyful about a rainbow blanket. Whether you’re knitting one for a nursery, a cozy couch throw, or a cherished gift, the combination of vibrant colors worked into soft, stitchable rows has a way of making every project feel like a celebration. Rainbow blankets have become one of the most beloved knitting projects in the fiber arts community, and it’s easy to understand why. They let you experiment with color in a way that other projects simply don’t, and the finished result is always eye-catching, always cheerful, and always worth the effort.

If you’ve been searching for the perfect rainbow blanket pattern, you’re in the right place. Below, The Knit Crew has rounded up eight stunning knitted rainbow blanket patterns that range from beginner-friendly to intermediate-level, so there’s something here for every skill level and every aesthetic. Whether you love bold, saturated stripes or prefer a subtle gradient that fades from one hue to the next, this list has you covered. Each pattern comes with a description of what makes it special, what yarn and needle types work best, and tips to help you get the most beautiful result.

Let’s dive in.

Why Knit a Rainbow Blanket?

Before we get into the patterns, it’s worth taking a moment to talk about why rainbow blankets are such satisfying knitting projects.

First, they solve the problem of yarn stash anxiety. Most knitters have a collection of leftover skeins in various colors, and a rainbow blanket is the perfect way to use them all up. Instead of letting half-used balls of yarn collect dust in a basket, you can turn them into something beautiful and functional.

Second, rainbow blankets are incredibly versatile. A softly graduated pastel rainbow blanket works beautifully in a baby’s nursery. A bold, jewel-toned version makes a statement as a couch throw. A chunky rainbow blanket knit in neutral-adjacent tones can feel modern and Scandinavian in style. The concept of the rainbow blanket is wide enough to accommodate nearly any design vision.

Third, working with multiple colors keeps knitting interesting. If you’ve ever gotten bored halfway through a large, single-color project, you know the struggle. Color transitions give you natural stopping points and a sense of progress that keeps motivation high from cast-on to bind-off.

Now, onto the patterns.

1. Classic Striped Rainbow Throw

The classic striped rainbow throw is the most iconic version of the rainbow blanket, and for good reason. This pattern involves casting on a comfortable width, then working in simple garter stitch or stockinette rows while changing colors at regular intervals. The result is a blanket that reads like a traditional rainbow — red, orange, yellow, green, blue, indigo, and violet — laid out in clean horizontal bands.

This is the perfect pattern for beginners because the stitch itself doesn’t require any technical complexity. The entire skill set you need is the ability to knit, purl (if you opt for stockinette), and join a new color. If you want perfectly clean color joins, work them at the beginning of a right-side row and weave in your ends carefully along the edges.

For this pattern, a medium-weight worsted yarn works beautifully. Choose seven distinct colors in equal quantities. If you’re making a lap blanket, plan for about 100 grams per color. For a full-size throw, you may want closer to 150 grams each. Straight needles in a US size 7 or 8 (4.5 to 5mm) will give you a nice, drapey fabric without holes.

The key to making this pattern look polished rather than basic is consistency. Decide upfront how wide each stripe will be and stick to it. Stripes of equal width look intentional and clean. You might also consider doing double the rows in each color so that you don’t have to weave in as many ends — just carry the yarn loosely up the side if you’re going back to a color within a few rows.

2. Gradient Fade Rainbow Blanket

If you love the idea of a rainbow blanket but find traditional hard-stripe transitions a little stark, a gradient fade rainbow blanket might be exactly what you’re looking for. This style uses a technique called “held strand” blending or simply alternates rows of two adjacent colors to create a soft, ombre-style transition between hues.

The effect is breathtaking. Instead of a clear line between red and orange, you get a fuzzy, painterly zone where the two colors mingle. This mimics the look of a watercolor painting and gives the blanket an almost dreamlike quality.

To achieve this look, you’ll work a set number of rows in your first color alone, then alternate one row of color one with one row of color two, then work a set of rows in color two alone before moving to the transition between color two and color three. The more rows you dedicate to the transition zone, the softer and more blended the gradient will appear.

This pattern works especially well with smooth, plied yarns rather than fuzzy or textured ones because the individual stitches need to be distinguishable for the blending effect to read clearly. Fingering weight or DK weight yarn on smaller needles will give you a finer fabric with more visible stitch definition, which enhances the gradient effect beautifully.

3. Modular Mitered Square Rainbow Blanket

For knitters who love a bit more structure and geometric interest, a modular mitered square blanket is an absolute showstopper. Each square is knit individually by casting on a large number of stitches, placing a marker in the center, and decreasing at the center marker on every right-side row until only a few stitches remain. The result is a perfect square with a diagonal ridge running through the center.

When you join these squares together — either by picking up stitches along the edges as you go or by seaming at the end — you create a quilt-like patchwork of color. Using one color per square and arranging them in rainbow order creates a vibrant, graphic blanket that looks far more complex than it actually is.

The genius of this pattern is that it’s endlessly customizable. You can make each square a single color, or you can use two colors in a single square for an ombre effect within the square itself. You can arrange the squares in a strict rainbow grid, or you can randomize them for a scrappy, playful look. You can even mix square sizes for a more eclectic design.

This is a great pattern for using up very small amounts of yarn because each square can be quite small. Fingering weight oddments are perfect here. It’s also an excellent carry-along project because you’re always just working one small square at a time.

4. Entrelac Rainbow Blanket

Entrelac is a knitting technique that creates a woven, basket-weave texture by working a series of small rectangles in alternating directions. The result looks impossibly complex — like actual woven fabric — but the method is more approachable than it appears once you understand the rhythm.

A rainbow entrelac blanket takes this already beautiful technique and supercharges it with color. By changing the color for each new rectangle or group of rectangles, you can work through the rainbow in a way that looks like shifting, overlapping tiles. The diagonal nature of entrelac means that the colors blend visually in a really interesting way, creating secondary mixes where adjacent rectangles meet.

This is not a beginner pattern — it requires comfort with picking up stitches, short rows, and a fairly complex workflow — but it is absolutely achievable for an intermediate knitter with patience and a willingness to follow a written or video tutorial for the basic entrelac setup. The payoff is extraordinary. An entrelac rainbow blanket looks like a work of art.

For yarn, choose something with a consistent texture and a high stitch definition. Smooth merino or a cotton blend will show off the entrelac structure beautifully.

5. Chunky Knit Rainbow Block Blanket

If you love the satisfaction of fast knitting and dramatic texture, a chunky knit rainbow block blanket is deeply satisfying to make. Using super-bulky yarn and large needles — US size 13 to 17 (9 to 12mm) — this blanket works up incredibly quickly. You can often complete a full-size throw in a weekend.

The design involves working large blocks or sections of color in a simple moss stitch, seed stitch, or basket weave pattern. These textured stitches look especially impressive in thick yarn because every bump and ridge is pronounced and visible from across the room.

Because chunky yarn can be quite expensive, this pattern is ideal for working with a small rainbow palette rather than seven individual hues. A three-color rainbow (warm, cool, and neutral, or simply three adjacent colors from the spectrum) still reads as a rainbow-inspired blanket while keeping the cost and yarn volume manageable.

This blanket also makes an incredible gift because it looks incredibly luxurious and expensive even when made with budget-friendly big-box store yarn. Nobody needs to know it took you forty-eight hours over two evenings.

6. Slip-Stitch Mosaic Rainbow Blanket

Mosaic knitting is a colorwork technique that creates intricate, geometric designs using only one color per row. You slip certain stitches (instead of knitting them) to create the appearance of two-color patterning without ever carrying a strand across the row or managing two yarns at once. This makes it far more beginner-friendly than traditional stranded colorwork like Fair Isle.

A slip-stitch mosaic rainbow blanket uses this technique to create zigzag patterns, diamond shapes, or geometric lattices that alternate between adjacent rainbow colors. The result looks like complex colorwork but is actually achievable by any knitter who can read a simple chart or follow a stitch repeat.

The visual effect is bold and graphic. Because each “design” color is held for two rows while the background color alternates, you get deep, rich stitch patterns that have a lot of visual weight. A rainbow version — working through red, orange, yellow, green, blue, and purple as the design colors against a white or cream background — creates something that feels both playful and sophisticated.

This pattern works best in DK or worsted weight yarn for good stitch definition, and it pairs beautifully with smooth, non-fuzzy fibers so that every slipped stitch reads clearly.

7. Linen Stitch Rainbow Blanket

The linen stitch (also called the fabric stitch) creates a dense, woven-looking fabric that is absolutely unlike standard knitted fabric in the most delightful way. The texture mimics woven linen cloth, with a tight horizontal grain that gives the blanket structure and body.

A linen stitch rainbow blanket works the color changes in exactly the same way as a classic striped blanket, but the fabric created has a much more artisanal, handwoven quality. It drapes differently, feels different in the hand, and photographs beautifully.

The linen stitch is worked by alternating knit and slip stitches with the yarn held in front, which means the fabric is slightly more dense and takes more yarn than a simple stockinette blanket. Plan for slightly more yardage per color than you would for a basic stripe pattern.

This blanket works especially well with cotton, linen-blend, or bamboo yarns because those fibers have the drape and slight sheen that enhance the woven-fabric illusion. It’s also a wonderful summer knitting project because the flat, dense fabric is breezy and less bulky than wool-based options.

8. Feather and Fan Rainbow Blanket

The feather and fan stitch (sometimes called old shale) is one of the most classic and beloved lace stitches in traditional knitting. It creates a rhythmic wave pattern of increases and decreases that produces beautiful scalloped edges and gentle ripples across the fabric. Knitters who learned from their grandmothers often have at least one feather and fan project in their history.

A feather and fan rainbow blanket is the most romantic and old-fashioned of all the rainbow options on this list. The colors flow through the waves and scallops in a way that feels organic and almost like something found in nature — like a tropical fish or the inside of a seashell. Because the stitch pattern naturally undulates, the color transitions feel softer and more fluid than they would in a flat stitch, even if you’re doing hard color changes.

The feather and fan pattern has a four-row repeat that is easy to memorize after just a few repeats, making it a wonderful project for relaxed, rhythmic knitting. It’s a bit more advanced than basic garter stitch but not as demanding as entrelac or mosaic work — a great choice for confident beginners or knitters who are ready to try their first lace-adjacent pattern.

This blanket is stunning in fingering or sock weight yarn, which lets the delicate wave structure shine. Plan for a longer project timeline with fine yarn, but also plan for a finished object that looks absolutely heirloom-worthy.

Tips for Knitting Any Rainbow Blanket

No matter which pattern you choose from this list, a few universal tips will help your rainbow blanket come out looking its best.

Choose your colors with intention. Before you cast on, lay your yarn choices out in order on a flat surface and step back to look at them from a distance. Make sure the transition from one color to the next feels smooth and that no single color jumps out as too jarring or too similar to its neighbor.

Weave in ends as you go. Rainbow blankets generate a lot of ends from all the color changes. Rather than saving them all for the end, weave in each tail as soon as you finish with that color. Your future self will be very grateful.

Swatch first. This is especially important for blankets because gauge affects both the drape and the finished size significantly. A few minutes of swatching will save you from making a blanket that turns out too stiff, too floppy, or too small.

Block your finished blanket. Wet blocking a knitted blanket — soaking it in cool water, gently squeezing out the moisture, and laying it flat to dry — evens out the stitches and makes every finished blanket look professionally made. This step is especially important for lace patterns like feather and fan, where blocking opens up the stitch pattern dramatically.

Have fun with it. Rainbow blankets are meant to be joyful projects. If you change your mind about a color partway through, change it. If you want to make the stripes wider or narrower, adjust. The beauty of a handknit rainbow blanket is that it is entirely your own.

Final Thoughts

Whether you’re a beginner reaching for your very first two-color project or an experienced knitter looking for a bold, impressive statement piece, there is a rainbow blanket pattern on this list for you.
