Why the Honeycomb Rainbow Blanket Is Worth Making

Before we dive into the pattern itself, let us talk about why this particular blanket has captured the hearts of so many crafters around the world.

The honeycomb stitch is one of those techniques that looks far more complicated than it actually is. When you first see a finished blanket with its raised, interlocking hexagonal texture, you might assume it requires years of experience. The truth is that the stitch is built from a simple combination of basic crochet techniques, and once you understand the rhythm of it, your hands will fall into a comfortable, almost meditative pattern.

The rainbow color scheme adds another layer of magic. There is a reason rainbow crafts never really go out of style. The progression from one vibrant hue to the next gives this blanket an energy that plain single-color throws simply cannot match. It makes a stunning gift for a new baby, a cheerful addition to a child’s bedroom, or a bold statement piece for any living space that could use a burst of color.

The size is also incredibly versatile. You can scale this pattern up or down depending on your intended use. Make it small for a baby lap blanket, medium for a cozy throw, or large enough to serve as a full bed covering.

Materials You Will Need

Getting your materials together before you begin is always a good idea. Having everything at hand means you can focus entirely on the rhythm of the work once you start.

Yarn: You will need a medium weight yarn, also known as worsted weight or category 4 yarn. For a full rainbow effect, choose colors in the following spectrum: red, orange, yellow, green, blue, indigo, and violet. You can add as many color transitions as you like, but these seven make up a classic rainbow. Plan on roughly 200 to 250 yards per color for a medium-sized throw blanket, though this will vary depending on your gauge and the finished size you are aiming for. A cotton-acrylic blend works beautifully for this pattern because it holds stitch definition well, which really lets the honeycomb texture shine through.

Hook: A size 5.0mm (H/8) crochet hook is the standard recommendation for worsted weight yarn. If your stitches tend to run tight, you might go up to a 5.5mm hook to ensure the fabric stays soft and flexible. If you crochet loosely, stick with the 5.0mm or even try a 4.5mm.

Notions: You will also want a yarn needle for weaving in ends, scissors, stitch markers to help keep your place, and a measuring tape. A row counter, either a physical one or an app on your phone, can also be helpful when you are tracking color changes.

Understanding the Honeycomb Stitch

The honeycomb effect in crochet is typically created using a combination of front post and back post double crochet stitches. If you are not familiar with these terms, here is a quick primer.

A double crochet (dc) is the standard upright stitch most crocheters learn early on. You yarn over, insert your hook into the stitch, pull up a loop, and work through two loops twice.

A front post double crochet (fpdc) is worked the same way, but instead of inserting your hook into the top of the stitch as usual, you insert it around the post of the stitch in the row below, going from the front, around the right, and back around to the front. This brings the stitch forward and creates raised texture on the surface facing you.

A back post double crochet (bpdc) is the opposite. You insert your hook around the post from the back of the work. This pushes the stitch backward and creates an indented line on the surface facing you.

By alternating front and back post stitches in specific groupings and offsetting them every few rows, you build up the interlocking raised pattern that mimics the look of a honeycomb. Once you crochet a few rows and begin to see the pattern emerge, it becomes intuitive.

Gauge

Before beginning your blanket, it is always a good idea to work up a small gauge swatch. Gauge matters most when size is critical, such as for garments, but for a blanket it is still worth checking so you can predict your finished dimensions.

Using the recommended hook and your chosen yarn, chain 18 and work the stitch pattern for 12 rows. Your swatch should measure approximately 4 inches wide by 4 inches tall if your gauge is on track. Adjust your hook size up or down as needed.

Pattern Instructions

Foundation

Chain a multiple of 4, plus 2. For a medium-sized throw blanket, casting on 106 stitches (which equals 26 sets of 4, plus 2) gives you a nice width of approximately 42 to 44 inches depending on your gauge. Adjust up or down based on your preferred finished width.

Row 1 (RS): Starting in the second chain from the hook, work 1 dc in each chain across. Turn. (You should have 105 dc stitches.)

Row 2 (WS): Ch 2 (does not count as a stitch here or throughout), work 1 dc in each stitch across. Turn.

Beginning the Honeycomb Pattern

Row 3 (RS): Ch 2, work 1 fpdc around the post of the next 2 stitches, then work 1 bpdc around the post of the next 2 stitches, repeat from to across to the last stitch, dc in the last stitch. Turn.

Row 4 (WS): Ch 2, work 1 bpdc around the post of the next 2 stitches, then work 1 fpdc around the post of the next 2 stitches, repeat from to across to the last stitch, dc in the last stitch. Turn.

Row 5 (RS): Ch 2, work 1 bpdc around the post of the next 2 stitches, then work 1 fpdc around the post of the next 2 stitches, repeat from to across to the last stitch, dc in the last stitch. Turn.

Row 6 (WS): Ch 2, work 1 fpdc around the post of the next 2 stitches, then work 1 bpdc around the post of the next 2 stitches, repeat from to across to the last stitch, dc in the last stitch. Turn.

These four rows (Rows 3 through 6) form the honeycomb repeat. Continue repeating Rows 3 through 6 until your blanket reaches the desired length, changing colors according to the color plan below.

Color Change Schedule

To achieve the rainbow effect, work a block of rows in each color before transitioning to the next. A clean look comes from changing colors at the start of a new row, always on the right side if possible, so the joins are consistent.

Work approximately 8 to 10 rows in each color. This gives you a satisfying stripe of color that is wide enough to really see the honeycomb texture before the next hue appears. The transitions can be worked as clean cuts and joins, or you can carry the yarn loosely up the side edge if you prefer fewer ends to weave in. For a rainbow, however, since the color changes are fairly spaced apart and you will not be returning to each color for a long stretch, cutting and joining tends to give the neatest result.

Begin with red and work through orange, yellow, green, blue, indigo, and violet in sequence. If you want a larger blanket, simply repeat the rainbow sequence from the beginning once you finish violet, creating a doubled rainbow effect.

For a more subtle gradient approach, you could also consider choosing yarn in ombre or self-striping options that already transition through rainbow hues. This simplifies the color change process significantly while still giving you that spectrum of color.

Finishing the Blanket

Once your blanket has reached your desired length, work two final rows of plain double crochet to mirror your foundation rows and give the piece a balanced, finished look on both ends.

Final Row 1: Ch 2, work 1 dc in each stitch across. Turn.
Final Row 2: Ch 2, work 1 dc in each stitch across. Fasten off.

Border

A simple border frames the blanket and gives it a polished, professional look. For a clean and classic finish, try the following.

Join your yarn at any corner with a slip stitch. Chain 1, then work 3 sc in the corner stitch. Continue working single crochet evenly along each edge, placing 3 sc in each corner stitch as you go. When you arrive back at the starting corner, slip stitch to the first sc to join. Fasten off and weave in all remaining ends.

If you want something with a little more dimension, a shell stitch border or a simple picot edge both complement the honeycomb texture beautifully without competing with it.

Tips for Success

Keep your tension consistent. Post stitches can sometimes pull tighter than regular stitches, which may cause your work to pucker or draw in at the sides. If you notice this happening, try loosening your grip slightly or going up a hook size. Taking a moment to check the sides of your work after every few rows can help you catch this early.

Mark your right side. Because post stitches work on both right and wrong sides, it can be easy to lose track of which side is which, especially when you are in the middle of a long project. Place a stitch marker or a small piece of contrasting yarn at the corner of your right side so you always know which direction you are heading.

Work your color ends in as you go. Waiting until the end to weave in every color change tail means you will be sitting with a mountain of ends at the finish line. Taking a few moments to weave in the tails from each color change as you work through your rows keeps things manageable.

Block your finished blanket. Blocking makes an enormous difference in the finished appearance of textured crochet. Wet blocking, which involves soaking the finished piece in cool water, gently squeezing out the excess, and laying it flat to dry in its desired shape, evens out the stitches and allows the honeycomb pattern to open up and settle beautifully. If you used an acrylic yarn, steam blocking with a garment steamer or by hovering a steam iron above the surface (without pressing down directly) will relax the fibers.

Photograph in good light. If you plan to share your finished blanket on social media or on a blog, natural light is your best friend. The colors in a rainbow blanket are vibrant and deserve to be shown off properly. Lay the blanket flat near a window during the daytime and let the light do the work.

Sizing Variations

The pattern as described creates a blanket approximately 42 inches wide. Here are a few simple adjustments you can make to customize the size.

For a baby blanket, cast on 54 stitches (13 sets of 4, plus 2) and work to a length of about 30 inches. This creates a lap-sized piece perfect for a stroller or crib.

For a lap throw, the pattern as written works beautifully as-is. Work to a length of around 50 to 55 inches.

For a full bed throw, cast on 162 stitches (40 sets of 4, plus 2) and work to a length of 65 to 70 inches. You will need significantly more yarn for this version, so plan your yardage accordingly before you begin.

Gift Ideas and Uses

The Honeycomb Rainbow Blanket makes one of the most memorable handmade gifts you can give. It is the kind of project that people recognize as genuinely labor-intensive and yet the finished result looks so cheerful and inviting that it immediately becomes a favorite in the home.

Consider gifting it at baby showers, where the bright rainbow colors bring a sense of joy and warmth without defaulting to traditional pink or blue. Teachers, especially those who work with young children, tend to love these blankets for their classrooms. They also make wonderful birthday gifts for anyone who appreciates color and texture.

For your own home, this blanket looks stunning draped over the back of a neutral sofa, where the colors really pop. It can anchor a reading nook, add warmth to a bedroom, or simply be the thing you reach for on cold evenings when you need something cozy.

Share Your Make

One of the best parts of the crafting community is how generously people share their work. If you make this blanket, consider sharing a photo and tagging it so other makers can find inspiration in your version. Every person who crochets this pattern brings something slightly different to it, whether through their choice of yarn weight, hook size, color palette, or finishing style. Seeing those variations is endlessly inspiring.

If you tweaked the pattern in any way, leave a note in the comments. Did you swap the color order? Did you add an extra color or try a different border stitch? Other crafters genuinely benefit from those small insights, and sharing them builds the kind of community that keeps this craft alive and evolving.
