I took the time to draw my frame full size, and I would highly recommend it.

I bought a roll of 36 inch wide drafting paper and a few rudimentary drafting tools, set aside a quiet Saturday afternoon, put on some good music, and enjoyed myself immensely.

The drawing helped me to confirm that my calculations were correct and that everything looked and felt right. As I build the frame I hold it up to the drawing to satisfy myself that everything is more or less where is should be.
