Crochet the Beautiful Tonnta Lightweight Scarf Pattern With Waves

Updated: 1 November 2026 by Sylwia (MyCrochetory)

This lightweight crochet scarf pattern happened almost by accident. I’d just finished my Tonnta Blanket, and I couldn’t stop staring at that wave stitch.

What would it look like as a scarf? I grabbed a ball of lace weight merino to find out, and the waves look even better hanging around your neck than on a blanket.

Tonnta means “waves” in Irish, and the name really says it all. Four soft waves run down the whole length, and the lace weight yarn keeps it light enough for spring mornings.

How the waves in this lightweight crochet scarf pattern work

Ever wondered how a wave gets into crochet? In this lightweight crochet scarf pattern, it’s all about where you add stitches and where you take them away.

Every wave has a peak, where you work (2dc, ch1, 2dc) into one stitch, and a valley, where 5 stitches squeeze into one with a dc5tog. Do that across the row, and the edge starts to rise and fall like water.

The scarf starts with 165 stitches, which gives you 4 waves across. Want a skinnier or a wider one? Just add or take away chains in multiples of 40.

One 4-row repeat for the whole lightweight crochet scarf pattern

The whole scarf is one 4-row repeat. Make Rows 3 to 6 a couple of times, and you’ll barely need to look at the pattern anymore.

Row 3 is front post double crochet, which pushes the stitches forward into those little raised lines. Rows 4 and 5 are the lacy part, and the stitches grow taller toward the middle of every wave, sc, hdc, dc and then tr.

Row 6 closes it all with double crochet, and you’re back at the start. Learn better by watching? I recorded a video tutorial for you, and it’s right above the pattern rows.

Self-striping yarn for your lightweight crochet scarf pattern

Self-striping yarn does all the color work here. I made Tonnta in Schoppel-Wolle Lace Ball 100, colorway Early Flowering, a self-striping 100% merino, and I’d still pick it today.

The colors change right along the waves, so every stripe follows the shape without you doing anything. Not a stripes person? A solid lace weight yarn makes the lace itself the star.

You’ll need about 1608 yards of lace weight yarn and a 2.5 mm hook.

Lace weight or fingering weight?

I went with lace weight, and it keeps this lightweight crochet scarf pattern airy and drapey. Fingering weight works too, just know the scarf comes out bigger and uses less yardage than the pattern says.

Got a Scheepjes Whirl cake staring at you from the stash? It’s fingering weight, so make a small swatch first and see how big your waves get.

Blocking brings out the waves

Fresh off the hook, the lace looks a bit crumpled, and that’s normal. Since it’s merino, I wet block.

I soak the scarf, stretch it out flat on a mat and pin it along the waves until it’s dry. That’s the moment the lace opens up and every wave gets its clean shape.

Lightweight crochet scarf pattern FAQ

Is this lightweight crochet scarf pattern good for beginners?

It’s an intermediate pattern. The stitches are basic, but you’ll need front post double crochet and the dc3tog and dc5tog clusters, and the video tutorial helps a lot with those.

What if I can’t find the yarn for this lightweight crochet scarf pattern?

Any self-striping lace weight yarn with long color changes gives a similar look. Short color changes make smaller, busier stripes.

Where can I find the stitch chart?
