I'm going nuts here. First off-I'm a relatively new weaver-about 3 months now. So far, I've been trying lots of different kitchen towels with mostly successes. Twice now, I have towels come out that are off-grain. Both times the warp has been for six towels, so a little longer than I'm doing for other towels. The ones today are a buffalo plaid. Four towels look good, two are off-grain. I know for certain that one of the two was the last one on the loom. Why is this happening? They look ridiculous when folded or hanging on a towel rack because the hems are wonky. I did the buffalo plaid in 2/2 twill. 20 epi and 20 ppi. The other ones were a herringbone twill pattern also 20 epi and 20 ppi. Any ideas would be so appreciated!

I don’t think it has anything to do with length of warp and one way to test that would to see what happens if you weave plain weave on the same warp. That diagonal really has torque. Changing the direction of the twill treadling may help. Instead of treadling 1234, try 4321. It is the opposite direction to how you threaded. Let us know if you try that and it helps. :)

Thank you! I'll give your ideas a try. And thank you for the videos. They have been so helpful and I'm learning so much!
