Well after some adjusting to make it fit the poles...here it is (haven't ironed it yet)!
Not quite as big as I hoped, but it isn't too bad I guess for a rustic wild west boyish tent.
I used left over fabrics, scrap (from old clothes), ribbon for seams and bamboo poles. Rubber feet stop it slipping and rings sewn on the inside of fabric to keep the poles in place.
More pics when it is party time.
