I picked up some Spud and Chloe super bulky merino-cotton yesterday, and interruped the linen clapotis to knit it into their boyfriend hat today.
The color work was a first for me and I didn't know to let the strands of unworked yarn hang loosely. The hat is nonethess very very cool, but it's now destined for the 6 year old, not the 18 year old.
Fortunately I have enough yarn left to reverse the colors and do a second hat, and this pattern is interesting enough to have a second go at it
