Here is a picture of two chairs I made from green Red and White Oak. The one on the left is from "Make a chair from a tree" by John Alexander. It has a rush seat and a Watco oil finish. I just finished the rocking chair from plans by Brian Boggs in Woodwork magazine from 1991. I have not made the seat yet for the rocking chair and am trying to decide what material to use. I would like to try a traditional hickory bark seat. Does anyone have a source for the hickory bark material at a reasonable cost? Any other seating suggestions? I would like to try another rocking chair next using the Fine Woodworking plans also by Brian Boggs. Thanks, Tom
