Below are some yarn suggestions for this pattern.
Maybe you have some Nightshades/Daylights leftover from your Nevasca shawl? My hat used a little less 30 grams of Harrisville Nightshades in Last Call.
Woolfolk TYND would make a great companion to a Harrisville Nightshades/Daylight in this pattern! Woolfolk is known for their extra fine, extra soft merino yarns, and it will be so cozy against your ears! (Is making a third hat too many??)
There’s no reason you couldn’t make this using Harrisville daylights instead!
