Inspiration comes when you least expect it. I was in London last fall for 100% Design. There were tons of beautiful things, but the plywood table that Carl Hansen built for their display (below) stuck with me. I wanted to copy it for my own dining table some day. That day just arrived.
This super long table struck me as the most elegant plywood construction I had ever seen. The joinery was also so easy to see and copy, I decided to take pics and bring the idea home. Key to the design was the closed ends, which make it very tidy and bold (but eliminates a seat on the end) and the double layer design, which makes it much stronger and heftier than typical plywood fare.
