What a Bobble Is and Why You'd Knit One
A bobble is a small, rounded bump you create on the surface of your knitted fabric by working multiple stitches into a single stitch, then decreasing them back down. The result looks like a tiny ball popping out from your knit. Bobbles add texture and visual interest to sweaters, blankets, hats, and scarves—they're especially popular on baby items and decorative pieces.
The basic bobble takes about five stitches worked into one, then decreased back to one stitch over four to six rows. Once you understand the pattern, you can place bobbles anywhere in your knitting by following your pattern instructions or placing them randomly for a playful effect.
Key Takeaways
- A bobble is made by increasing multiple stitches into one stitch, working several rows on those stitches, then decreasing them back to one.
- The most common bobble uses five stitches increased into one, worked over four rows, then decreased on the fifth row.
- You work bobbles on the right side of your fabric so they puff outward visibly.
- Bobbles work best in worsted weight yarn or heavier; thinner yarns make bobbles that are hard to see.
- Counting rows carefully and keeping your tension even prevents bobbles from looking lopsided or too loose.
The Standard Five-Stitch Bobble Pattern
The most common bobble pattern works like this: on your right-side row, you'll increase five stitches into one stitch, work four rows on just those five stitches, then decrease all five back down to one on the final row. This creates a compact, rounded bump.
Here's the exact sequence. When you reach the stitch where you want your bobble, work into it five times instead of once. You do this by knitting into the front of the stitch, then without slipping it off the needle, knitting into the back of the same stitch, then the front again, then the back again, then the front one more time. Now slip the original stitch off the needle—you have five stitches on your right needle where there was one before.
Turn your work around (even though you're in the middle of a row). You're now working back and forth on just these five stitches. Purl across all five. Turn. Knit across all five. Turn. Purl across all five. Turn. Knit across all five one more time. You've now completed four rows on your bobble stitches.
On the fifth row, you'll decrease all five stitches back to one. Slip the first stitch knitwise, knit the next two stitches together, pass the slipped stitch over the decrease, then knit the last two stitches together. You're back to one stitch. Continue knitting your main fabric row as normal.
Working Bobbles Into Your Pattern
If your pattern tells you where to place bobbles, it will usually say something like "MB" (make bobble) at a specific point in a row. When you see that abbreviation, stop and work your bobble right there using the stitch the pattern indicates, then continue with the rest of the row.
Some patterns space bobbles evenly—for example, one bobble every ten stitches across a row, then repeat that row every eight rows. Other patterns scatter them randomly for a more organic look. Read your pattern instructions carefully to see whether bobbles go on right-side rows only, or whether some appear on wrong-side rows (which changes how they sit).
If you're designing your own bobble placement, mark it on your pattern or use stitch markers to remind yourself where they go. It's straightforward to forget mid-row and accidentally skip one.
Common Mistakes That Make Bobbles Look Wrong
The most frequent error is working your bobble stitches too tightly. When you increase five stitches into one, pull your yarn snug but not so tight that the base of the bobble puckers. If the bobble feels hard to work and the stitches look cramped, you're pulling too hard. Loosen your tension slightly and the bobble will sit more naturally.
Another common problem is losing track of which row you're on while working the bobble. Because you turn your work mid-row, it's straightforward to lose count. Use a row counter or write down "Row 1, Row 2" on a scrap of paper and check off each one as you finish it. Miscounting means your bobble will be lopsided or too tall.
Bobbles also look flat and invisible in very thin yarn. If you're using fingering weight or lace weight, bobbles won't show up well. They work best in worsted weight, bulky, or super bulky yarn where the texture is obvious.
Yarn Weight and Bobble Size
The thickness of your yarn determines how prominent your bobble will be. In worsted weight (medium thickness), a standard five-stitch bobble is about the size of a small marble and very noticeable. In bulky yarn, the same bobble looks larger and puffier. In fingering weight, it barely shows.
If you want smaller bobbles in worsted weight, you can make a three-stitch bobble instead: increase three stitches into one, work two rows, then decrease. If you want larger bobbles, increase seven stitches into one and work six rows before decreasing. The principle stays the same—more stitches and more rows equal a bigger bobble.
Fixing a Bobble That Went Wrong
If you finish a bobble and it looks too loose, bunched, or uneven, you have two choices. If you caught the mistake when ready, you can unravel just the bobble rows, drop back to the base stitch, and redo it. Carefully pull the yarn and let the stitches unravel until you're back to the single stitch where the bobble started, then work it again.
If the bobble is already joined back into your main fabric and you don't want to unravel, you can often tighten it by weaving in the yarn tail from the bobble base very snugly. This pulls the base of the bobble tighter and makes it look more defined. It's not perfect, but it's a quick fix if you're near the end of a project.
Bobbles on Different Stitch Patterns
Bobbles work on stockinette stitch (knit on right side, purl on wrong side) most easily because you're not fighting against a textured background. They also look good on reverse stockinette, garter stitch, and ribbed fabrics. The bobble will stand out more against a smooth background and blend slightly into a textured one.
If you're placing bobbles on a cable or lace pattern, plan ahead so the bobble doesn't interrupt a cable cross or a yarn-over decrease. Most patterns that use bobbles already account for this, but if you're improvising, sketch it out first to make sure the bobble sits in a stable part of the stitch pattern.
Frequently Asked Questions
Can I make a bobble on the wrong side of my fabric?
Yes, but it will puff inward instead of outward. This is sometimes done intentionally for a subtle texture on the back of a garment. Follow the same steps, but work the bobble on a wrong-side row. The bump will sit on the inside of your finished piece.
What if I drop a stitch while working my bobble?
Stop when ready and pick it up with a crochet hook before it runs down. Because you're working back and forth on just five stitches, a dropped stitch can unravel quickly. If it's already run several rows, you may need to unravel the entire bobble and start over.
Do I have to use the exact five-stitch bobble pattern?
No. You can make three-stitch, seven-stitch, or even nine-stitch bobbles. Fewer stitches make a tighter, smaller bump; more stitches make a looser, larger one. Experiment on a swatch to see what size you like before adding bobbles to your main project.
How do I keep my bobbles from looking lumpy?
Keep your tension even throughout the bobble rows and make sure you're decreasing correctly on the final row. Uneven tension makes bobbles look misshapen. Also, don't pull the yarn too tight when you first increase the five stitches into one—this is the most common cause of a lumpy base.
Can I add bobbles to a finished piece?
You can embroider a bobble-like texture onto finished knitting using a needle and yarn, but you cannot knit a true bobble into an already-finished piece. If you want bobbles, they need to be worked as you knit. Plan ahead and add them to your pattern before you cast on.
