Here is my yarn usage per chart:
Chart 1: 4.9 g
Chart 2, repeat 1: 11.7 g
Chart 2, repeat 2: 18.8 g
Chart 2, repeat 3: 26.8 g
Chart 2, repeat 4: 33.5 g
Chart 2, repeat 5: 41.1 g
The yarn usage is essentially linear, as this chart shows.
I pulled out my stash of leftover Luxe yarn as I am thinking of binding off in a contrasting color. I really like contrast bind offs, and it would allow me to use up my last skein without worrying about keeping enough in reserve for the bind off. Here are the colors I have to choose from.
Pattern: MagicWaves Triangle by Kieran Foley & Nim Teasdale
Yarn: The Unique Sheep Luxe in Snow Glint
Needles: US 4 (3.5 mm)
