"As a designer who’s often most comfortable knitting for the depths of winter, when designing this set I had to consider what spring means to me, and what I look forward to. New growth is undeniably one of the things I’m drawn to the most, but the leafy lace motif used in this hat and cowl is also very geometric and repetitive, making it a soothing project to knit."
