Additional Notes
I took yarn info from the video as the written pattern gives only general information. I left weight blank as the yarns are 2 different weights. Designer suggests carrying a metallic thread with Safran (sport weight) for extra brightness if desired or using a yarn that already has metallic thread like Garnset Metallic (light fingering), but only gives one hook size.
