I've just finished a group she has labeled Escalator. The name comes from a section made up of a row of half stitches that are worked uphill.
In this example, you work the section above the line all the way to the end and then use the pair at the base of the line to work half stitch to the point at the top of the line. Now you're ready to work the section below the line. And you get this one in the middle.
Each of these samples uses this escalator technique, although in different ways.
My absolute favorite of this trio is the edging at the right. It has some of my favorite techniques like the spider ground and the Scotch broom trails. I would have carried on with it but I'm anxious to get moving on.
