Free Pattern: Message in a Bobble – Harmony Blanket Square #19

Welcome back to the Harmony Blanket series! If you’ve been following along, you already know how much joy this project brings to so many crochet enthusiasts around the world. Each square in this collection tells its own little story, introduces a new technique, and adds another layer of beauty and texture to what will eventually become a stunning, heirloom-quality blanket. Today we’re diving into Square #19, and it’s one that I’m especially excited to share with you: Message in a Bobble.

This square is a showstopper. Bobble stitches have a way of adding incredible three-dimensional texture and visual interest that flat stitches simply can’t replicate, and in this design, those bobbles are arranged in a way that almost feels like they’re whispering something to you — a gentle, tactile message worked right into the fabric of your yarn. Whether you’re a longtime follower of the Harmony Blanket series or you’ve just stumbled upon this post while searching for your next crochet project, you’re in exactly the right place.

Let’s get into everything you need to know to complete this beautiful square, from materials and abbreviations all the way through the full written pattern.

A Little About the Harmony Blanket Series

Before we jump into the pattern itself, a quick word for those who are new here. The Harmony Blanket is a year-long (or longer, depending on your pace — no judgment here!) crochet-along project made up of individual squares that are each approximately the same finished size. When completed and joined together, the squares create a rich, varied blanket that celebrates the full range of crochet texture, color, and stitch work.

Each square in the series uses a consistent gauge and yarn weight so that all the pieces play nicely together at the end, even though the individual techniques vary widely from square to square. Some squares are delicate and lacy. Some are bold and graphic. Some, like today’s Message in a Bobble, are all about glorious, puffed-up texture that practically leaps off the fabric.

If you’re new to the series, I highly recommend starting from Square #1 and working your way through, but each square is also fully self-contained. You can make Message in a Bobble as a standalone dishcloth, a decorative pillow panel, a single granny square to add to any blanket project, or simply as a practice piece to sharpen your bobble stitch skills.

What Makes the Message in a Bobble Square Special

Bobble stitches are made by working multiple incomplete double crochets into the same stitch and then closing them all together at the top. The result is a raised, rounded bump that sits on the surface of the fabric — and because the bobbles pop toward the back of your work as you crochet, you’ll notice they appear most prominently on the opposite side from where you’re working. This means it’s worth checking your work regularly from the “right side” to make sure those beautiful bobbles are popping in the right direction.

What makes Square #19 especially interesting is the arrangement of the bobbles. Unlike some bobble patterns where the bobbles are scattered randomly or placed at predictable regular intervals, this design uses the bobbles to create a subtle geometric rhythm — almost like dots and dashes, or like beads threaded on a string. When you step back and look at the finished square, there’s a lovely sense of movement and intention in the texture, as if the yarn itself is trying to tell you something. That’s the “message” in the name, and I absolutely love the poetry of it.

Materials You Will Need

One of the best things about this square is that it’s approachable for a wide range of skill levels. If you’ve completed a double crochet before, you already have the fundamental building block for the bobble stitch. Here’s what you’ll want to gather before you sit down to start:

Yarn: Worsted weight yarn (approximately 50 to 75 meters / 55 to 82 yards depending on your gauge and color choices). I used a smooth, mercerized cotton for this square because the stitch definition is beautiful in cotton, but an acrylic, wool, or wool-blend yarn works wonderfully too. Choose whatever fits the color story of your Harmony Blanket.

Hook: 4.5mm (US 7) crochet hook, or the size needed to achieve your gauge.

Notions: Scissors, a yarn needle for weaving in ends, and stitch markers if you find them helpful for keeping your place in the pattern.

Gauge: 14 stitches and 16 rows in double crochet = 4 inches (10 cm) square. Always make a gauge swatch before beginning if you’re working this square to join with the rest of your Harmony Blanket, as consistent sizing across all squares will make the finishing process much easier.

Finished Size: Approximately 7 inches by 7 inches (18 cm by 18 cm) after blocking, which is consistent with the other squares in the Harmony Blanket series.

Abbreviations Used in This Pattern

Here’s a quick reference guide to all the abbreviations you’ll encounter in the written pattern below. If any of these are new to you, don’t worry — I’ve included a technique note section after the abbreviations that walks you through each special stitch.

ch — chain

sl st — slip stitch

sc — single crochet

dc — double crochet

bob — bobble stitch (see technique note below)

st(s) — stitch(es)

sp — space

RS — right side

WS — wrong side

rep — repeat

beg — beginning

rem — remaining

sk — skip

t-ch — turning chain

Technique Note: How to Make the Bobble Stitch

The bobble stitch used in this pattern is a 5-double-crochet bobble. Here’s how to work it step by step:

Insert your hook into the designated stitch or space. Yarn over, pull up a loop (you now have 3 loops on your hook). Yarn over and pull through 2 loops (2 loops remain on hook). You have just worked one incomplete double crochet.

Without finishing that double crochet, insert your hook into the same stitch again. Yarn over, pull up a loop (4 loops on hook). Yarn over and pull through 2 loops (3 loops remain). You have worked two incomplete double crochets into the same stitch.

Repeat this process three more times in the same stitch until you have 6 loops on your hook (five incomplete double crochets worked into the same place). Now yarn over and pull through all 6 loops at once to close the bobble. One single chain stitch is often added after the bobble to lock it in place — the pattern will note when this applies.

Remember: as you work on the right side of your fabric, the bobble will push toward the wrong side. When you turn your work and look at the right side, you’ll see the bobble popping toward you beautifully. This is normal and intentional, so resist the urge to squish those bobbles back through — they’re exactly where they should be.

Color Notes

This square looks wonderful in a single color, especially in a richly saturated shade that shows off the texture of the bobbles against the flatter background stitches. If you want more visual drama, you can work the bobbles in a contrasting color using the intarsia or carry-along method, though that does add some complexity. For the written pattern below, I’ll assume you’re working in a single color, which is how I crocheted my sample square and how it photographs most beautifully.

If you’re working this as part of your Harmony Blanket, refer to your overall color palette plan to decide which shade works best in position #19.

Block the finished square to your target dimensions (approximately 7 inches by 7 inches) using your preferred blocking method.

Tips for Success With This Pattern

A few things I’ve learned from working this square myself, and from watching others tackle it in our community group:

Count your bobbles carefully. The alternating placement of the bobbles between rows is what creates that lovely offset rhythm in the finished square. If you lose track of which row you’re on, your bobbles might line up in columns instead of the staggered pattern. Take a moment after each RS row to look at your work from the right side and confirm that the bobbles are sitting in the offset positions.

Don’t pull your yarn too tight when closing a bobble. It’s tempting to yank that final loop closed firmly, but doing so can cause the surrounding stitches to pucker and distort. A firm but gentle pull gives you a nicely rounded bobble without distorting the fabric around it.

Blocking makes an enormous difference. Bobble stitches can make the fabric look a bit uneven and bunchy before blocking, especially if you’re using a natural fiber. Don’t panic when you look at your finished square before it’s been wet-blocked or steam-blocked. Lay it flat, coax it into shape, pin it if needed, and let it dry fully. You’ll be amazed at the transformation.

Check your stitch count frequently. The bobble stitch can occasionally cause confusion about where the next stitch begins and ends, especially when you’re new to them. Take care not to accidentally skip a stitch immediately after a bobble, and make sure you’re crocheting into the top of each bobble (not into the extra lock-off chain if you’ve added one) on the wrong-side rows.

Consistent tension is your best friend. As with all texture stitches, the more consistent your tension, the more even and polished the finished fabric will look. If you notice yourself tensing up as you work the bobbles (it happens to all of us!), take a breath and loosen your grip on the yarn slightly.

Joining This Square to Your Harmony Blanket

When you’ve completed all 20 squares in the Harmony Blanket series (or however many you’re making), you’ll join them using your preferred join method. The most popular choices for textured squares like this one are the flat slip stitch join, the join-as-you-go method, or a whipstitch join worked through the back loops only. All three methods give a tidy finish that doesn’t compete visually with the gorgeous texture of the individual squares.

For a blanket that prioritizes texture and dimension, I’d lean toward the join-as-you-go method or a simple single crochet join worked from the wrong side — both keep the seam on the back of the blanket so the right side remains all about those beautiful stitches.

Yarn Substitution Ideas

While I worked my sample in a DK-weight cotton held double to achieve worsted weight, here are some yarns that work beautifully for bobble-stitch projects like this one:

A smooth merino wool gives incredible stitch definition and is a dream to block. A cotton-acrylic blend is forgiving for beginners and holds its shape well over time. A plant-fiber yarn like bamboo or linen gives the bobbles a slightly flatter profile but a lovely drape. Bulkier yarns can be used if you scale the hook up accordingly, though the finished square will be larger and you’d need to adjust your stitch count to match the other squares in your blanket.

Whatever yarn you choose, make sure it’s not a furry, hairy, or heavily textured yarn. Mohair and boucle yarns, while beautiful in other applications, will hide your bobbles completely. The whole point of this square is that texture, so give it a yarn that lets it shine.

What’s Coming Next in the Harmony Blanket Series

If you’re working through the series in order, Square #20 is just around the corner, and I can promise it’s another wonderful one. We’ll be exploring a completely different approach to surface texture — much lighter and more open in feel than today’s bobble-heavy design, which makes it the perfect visual counterpart to this square when they sit side by side in the finished blanket.

In the meantime, I’d absolutely love to see your finished Message in a Bobble squares. If you share your work on Instagram or in our community group, please use the hashtag so I can find your photos and cheer you on. Seeing your finished work — in all your wonderful color choices and yarn selections — is genuinely one of the greatest joys of sharing these patterns.

Final Thoughts

The Message in a Bobble square is one of those patterns that feels like more than the sum of its parts. It’s a straightforward repeat, an accessible stitch, a simple layout — and yet the finished result has this quality of intention and rhythm that makes it feel like something meaningful was woven into the yarn itself. Maybe that’s the real message: that every stitch you place is a small act of care, and when you put enough of them together, they become something beautiful.

Thank you so much for crocheting along with the Harmony Blanket series. Whether this is your first square or your nineteenth, I hope you’re feeling proud of what you’re creating. Keep going — the finished blanket is going to be absolutely extraordinary.

Happy crocheting, and I’ll see you for Square #20!
