Triangle scarf with a chevron lace center

A chevron-lace triangle scarf built from a magic circle with simple color blocking.

Level: Intermediate
Time: 4-6 hours
Yarn: Worsted

Start with a magic circle and work the first round to set up the triangle's point.
Turn and begin Row 2, which establishes the treble crochet increase at the scarf's center.
Repeat the core row, working double crochet and chain-1 across and increasing at the same treble stitch each time.
Change colors again for the third stretch, then finish with the longest final stretch of one color.
Work all forty rows this way, letting the triangle widen steadily from the center increase.
Weave in ends and trim once the last row is complete.

About This Pattern

A triangle scarf earns its spot in a collection by being the piece you reach for without thinking. This one starts small and grows outward, the kind of project that fits in a bag for a waiting room or a long commute. It sits between lace and solid work, open enough to feel light.

The technique here is a center increase worked through a repeated double crochet and treble crochet combination, with chain-1 spaces doing the work of texture. Row 2 sets the increase point at the treble stitch, and every row after echoes it. It is simple math repeated with attention.

Finished, it is a triangle built in bands of color, forty rows deep from magic circle to final edge. The chain-5 spaces at each side give it a soft, scalloped border. It drapes more than it insulates, which is exactly the point of a scarf like this.

Common mistakes

Losing track of the increase stitch Mark the treble crochet from the previous row with a stitch marker before you start the next row. It keeps the center point from drifting off-center.
Skipping the chain-5 as a stitch Remember the chain-5 counts as a treble crochet plus a chain-1 space. Work into it at the row's end instead of passing over it.
Forgetting the color sequence Write down the row count for each color before starting, since the lengths change partway through the scarf. A sticky note on your pattern saves a lot of frogging.
Tight magic circle, loose first round Pull the magic circle closed firmly but keep the first round's stitches relaxed. A tight start combined with a tight round distorts the triangle's point.
Uneven chain-1 spaces Keep chain-1 spaces the same size as your double crochet stitches throughout. Inconsistent spacing shows up clearly in the open lace texture.

Main Pattern

The first color is used for a total of 20 rows.

Change the yarn color as desired for aesthetic variation after every couple of rows or as specified: second color for 5 rows; third color for 5 rows; final color for 10 rows.

The entire scarf consists of a total of 40 rows.

Row 1Begin with a magic circle; Chain 5 (this counts as your first treble crochet plus a chain-1 space); in the magic circle place 1 double crochet, chain 1, 1 treble crochet; repeat this sequence once (1 double crochet, chain 1, 1 treble crochet) within the magic circle; close the circle.

Row 2Chain 5 and turn your work (this counts as a treble crochet and a chain-1 space); in the first chain-1 space, work 1 double crochet, chain 1; double crochet in the next double crochet, chain 1; in the treble stitch, work an increase: double crochet, chain 1, treble crochet in the same stitch, chain 1, double crochet in the same stitch; chain 1, then double crochet in the next double crochet, chain 1; in the chain-5 space, double crochet, chain 1, and finish with a treble crochet.

Rows 3–40Repeat Row (The Pattern's Core): Chain 5 and turn your work; in the first chain space, double crochet, chain 1; continue with double crochet, chain 1 in each stitch across until you reach the increase point (treble stitch) from the previous row; work the increase in the treble stitch: double crochet, chain 1, treble crochet, chain 1, and double crochet, all in the same treble stitch from the previous row; continue double crochet, chain 1 in each stitch until the end; in the final chain-5 space of the row, double crochet, chain 1, and end with a treble crochet.

Assembly

Step 1Secure and trim any loose ends with a scissors and yarn needle.

Finishing

Weave in the yarn tail from the magic circle at the scarf's point first, since it is the hardest to find later.
Weave in each color-change end along the edge where it occurs, keeping tension even with the surrounding chain spaces.
Trim all ends close to the fabric with scissors once every tail is secured.

Why it works

The increase always lands in the same treble crochet stitch from the previous row, which is what keeps the triangle symmetrical as it grows.

The piece is worked flat and turned after every row rather than joined in rounds, which is what allows the center point to open into a wide triangle instead of a circle.

The chain-5 at the start of each row doubles as both a turning chain and a stitch, which is why it gets worked into at the row's end.

What it becomes

Wrapped once around the neck over a sweater, where the open chain spaces add texture without bulk.
Draped over the shoulders as a shawl substitute, paired with a simple solid-color coat.
Folded into a bag as a travel layer for cool evenings, easy to pull out and wear in seconds.

FAQ

Why does the scarf start with a chain-5 instead of a regular stitch?

The chain-5 stands in for a treble crochet plus a chain-1 space, which is how the pattern begins each row. It saves working a separate stitch at the start.

Can I use a different color sequence than the one given?

Yes, the color changes are for aesthetic variation and don't affect the stitch pattern. Just keep track of how many rows you've worked in each color.

Why does the triangle only increase at one point?

The increase is worked at the same treble crochet stitch every row, which is what shapes the triangle. Everywhere else, the double crochet and chain-1 repeat stays flat.
