The short answer
For cold weather, choose wool or a wool blend (merino, cashmere or mohair) over acrylic for warmth, in a size around 40 to 60 inches across so it knots easily at the front. Ties at the corners make a neat knot simpler. Crochet versions are airier and more textured; knits sit smoother.
What to look for
Choosing a knit or crochet triangle

|---|---|---|
| Fiber | Decides warmth, softness and itch | Wool, merino, cashmere, mohair or a blend; read the percentages |
| Size | Decides which knots work | About 40 to 60 in across the long edge for the neck. Size guide |
| Ties or corners | Ties make small scarves easy to knot | Ties for front knots; longer corners for drapes |
| Gauge | Chunky reads cozy; fine reads polished | Chunky for coats; fine or brushed under collars |
| Edges | Edges curl on plain stockinette | A garter, seed or ribbed border, or a crochet edge |

How to wear it
The two knots for a knit triangle are the front knot (point at the back, ends tied in front) and the bib (point at the front, knot at the back). The Zoe Report adds the shoulder drape for longer scarves and a close, double knotted neck wrap for windy days. In Cambridge Day’s street report, people wore them over coats, sweaters and blazers.

Care
Hand wash wool knits in lukewarm water and dry them flat. Woolmark warns that hanging knitwear to dry stretches it. More in how to wash a scarf.
Questions people ask
What is the difference between a knit and a crochet triangle scarf?
Knitting makes rows of interlocking loops, giving a smooth, stretchy fabric that sits close to the neck. Crochet builds each stitch on its own, so it tends to be more open and textured, with scalloped or shell edges. Both can be warm in wool.
Is acrylic OK for a knit triangle scarf?
It is cheaper and easy to wash, but it does not breathe or hold warmth the way wool does and can pill. If wool itches, look for merino, cashmere or a wool and cotton blend, and read the fiber content on the listing.
Should a knit triangle scarf have ties?
Ties are optional. They make a small scarf easier to knot at the front or the back. Without ties you need longer corners, so a scarf without ties should be a little larger.
