As someone who is always building and upcycling furniture. Hairpin legs are something that I am always in need of. For the past 2 years I have bounced back and forth with 4 different suppliers. The lead time was always too long and I never had them quite when I needed them. This lead me to the decision to solve the problem for myself and others. I recently purchased a wholesale lot of 100 14'' hairpin legs both for personal use and for wholesale. They are available locally at Hawthorne Vintage and online on Etsy.
Here the legs are pictured on my most recently completed coffee table.
