Flat patterns

This is the front of my chair with the appropriate cuts identified. (This is the outside of the chair) This is the back or inside of the chair with all the appropriate cutc identified. I only used curve cuts by removing the top layer and direct slices that go 9mm deep.
This is the flat pattern with dimensions. This demonstrates an economic use of material as it is just less than 1830 wide and exactly 1220 tall. The thickness is 10mm.
