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!
