The stitch for week 19 of TAST is the Half Chevron stitch.
I liked working with the Chevron stitch but did not have fun with the Half Chevron. I think that I did the last part of the stitch wrong because I do not have a continuous line but when I tried it that way I had other problems. I could not find many online resources such as videos for this stitch and it was not in any of my books.
Anyway, I am glad that I was at least able to complete an attempt at this stitch.
