Just like with the yurt, I used 35"-36" Boatshrunk Sunforger canvas for all the fabric components of the tent. I found out during the sewing of the wall panels that the overall width of the canvas I was using was 35" versus how it is sold at 36". The one inch difference in width affected the overall dimensions of my tent. I also used a flat felled seam for all seams, except for the hems.
