The half double slip stitch in this pattern is not commonly used, but it is easy to work and can be used to create a beautiful knit- look fabric. Practice this stitch until you have mastered it and it will soon be one of your favorites. A half double slip stitch is similar to a half double crochet in that it has 3 loops that you can see when looking at the completed stitch. There are the front and back loops at the top of the stitch, but there is also what I term a “lower loop,” which lays on the wrong side of the stitch. As you are working back across a row of half double slip stitch, you will find this lower loop positioned on the face of your work, directly below the front loop. When working in back loops only across a row of half double slip stitch, the front and lower loops will remain unworked and create the knit- look ribbing on the side facing you. When working in the lower loops only across a row of half double slip stitch, the front and back loops will remain unworked and create the knit- look ribbing on the side facing away from you.
