I have been interested in making a Whelen for some time myself. When you look at the original drawings and pictures in his books, the tent back is always made from three pieces of fabric. Judging by the six foot width he prescribes, it looks like two 30 inch piece set off by a one foot strip in the middle, and the wings are made of three sections as well.
Is this for strength? Or was it because the fabric came in 30 inch widths? I would think the additional seams would strengthen it quite a bit and the back panel would take some wind load in a good storm.
So if I get 40 inch fabric, should I cut it to allow for these seems? I am leaning that way even if it is more work. What is your take on it?
Thanks,
Bill
