Darn That Hole

This isn't really about math, but I'm working on my next show about darning holes. This is something a lot of knitters avoid, but the skills involved can also be used to seamlessly complete garments using kitchener stitch, which is basically one long row of darning, or add color details by darning on top of existing knit fabric (sometimes called swiss darning or duplicate stitch). If you want to follow along, dig up or create a gauge swatch that includes garter stitch, ribbing and stockinette stitch and have a good darning needle (I prefer curved ones) and yarn of the same weight, but different color, handy.
