you poor thing.... waist the money and buy one already made. No, I didnt, but all most. I got 2 out of 1 piece of 1/2 inch piece of plywood. put cotton batting on it and cover with heavy muslin or canvas. It has been recovered several times. the ply has not come unglued. I have had it 10yrs. love it. Mine is 44 X 60.
good luck.
