I started a new weaving today, for an invitational coming up in September. Step one is to weave a small sample to determine aspect ratio. This one measures in at exactly 120 picks per inch in double twill. Warp sett is 63.4 epi. Dividing ppi by epi, we get 1.89 for the aspect ratio, so I will multiply the total picks in the file by 1.89 to get the new file size.
Lynette asked about granite weave. I'm embarrassed to say that I can't remember where I first encountered it; I only know that it was in an OLD weaving book. Bhakti and I did include information on how to draft granite weaves on pages 103-106 of The Woven Pixel; check it out if you have the book (and if you don't have it, look in the sidebar for a link).
And about that black glove—it is creepy. I walked the same route today, and the glove is still there, but it has moved about 10 feet further west. Hm-m-m.
