Its made of birch plywood 1/2" thick with a slight curve applied (I was shooting for more curvature, but hey), backed with wool felt and faced with 6-7 oz leather. The arm pad is seuede with cotton batting underneath (I was hoping for wool, but cotton is cheap). Final dimensions are approximately 20.5 x 29.5 inches.
As you can see, I did make some modern allowances, such as the use of modern upholstery tacks to help attach the leather to the back (I originally had fewer, strategically placed tacks, my wife "filled it in" because she thought it looked nicer that way).
The face was designed by me and painted by my wife.
Still some adjstments to be made. The main enarm needs to be trimmed shorter, and I need to add the guige (the attaching points are on there, as you can see). Other than that, I'm pretty happy with it.
My next project is to make a kite shield :)
