Merel Karhof has a knack for harnessing breezes and turning them into fun, sustainable goods we can use. Merel Karhof has been using the breeze as muse for years, finding new ways to spin airflow into creative gold. Most notable, perhaps, is the London-based designer’s Wind Knitting Machine, which united a metal mill and loom to make one-of-a-kind scarves. Her ongoing Energy Harvesters series (I, II, III, and IV) underscores her continued fascination with the invisible force. And her latest project, a furniture collection, is not only ingenious but it’s the most ambitious yet.
