After a couple of hiccups (threading error), I have finally started weaving the runner.
I have chosen a natural colour for the warp and tabby weft, and a navy for the pattern weft. I thought this strong colour contrast would help in seeing the pattern develop, show any errors more quickly, and give a more traditional look. I thought the sheen of a mercerized cotton would look nice.
So far, I think it is weaving up nicely.
