I am a maker of things.
After completing the garden pergola recently I had some left over oak.
Perhaps an Oak seat under an Oak tree would be good.
The most comfortable chair I have is the classic Ikea POÄNG
I transfer the section as a full scale rod on to a sheet of hardboard and redraw with the oak in mind instead of the Ikea laminated birch.
The parts are fabricated.
Green oak is lovely to work with, I work methodically with a gentle rhythm - unhurried.
I move outside and assemble the parts for the frame.
