This is the border design I used for Oaxaca. It's a laid filling stitch. That means that you lay in some long stitches and then you lay other stitches over them creating a pattern.
It's always a surprise when we think we're finished stitching, and then notice that a single stitch was missed. Well, I noticed a missed stitch in this border. See if you can find it. Hopefully, you'll find only one!
