I can't swear this will be the last gamp post. It's been so much fun I have to keep talking about it.
On the left is reverse twill, Chandler calls it vertical herringbone. The picture on the right is a 2/2 twill. I like the bolder look of the 2/2 twill. Here's a close up of the two twills. The plain weave in the center is woven with sewing thread and will be the turn under for the hem. I may have enough warp for one more (towel, napkin, whatever) maybe idiot's twill.
