Overview
This triangle-shaped lace scarf is worked from end-to-end with increases to the midpoint, then mirroring decreases.
The pattern is provided both as charts for two different sizes – an ascot size and a larger scarf.
While some rows are listed as wrong vs. right side rows, you are always knitting. The right vs. wrong just means that the increases should be on the left when you’re on a “right-side” row.

A note on gauge
Since this is a pretty open lace pattern, the gauge is less specific. I used US size 10 needles with a lace weight yarn, but you can go up or down for a more airy or tighter fabric.
