This pattern is based on simple stockinette stitch and creates soft creased fabric. I used it in Shar-Pei Mitts.
This technique allows you to create horizontal tucks on the stockinette stitch fabric, so that in the end your garment has soft drapes everywhere. This kind of fabric is also known as cloque. The effect is created by knitting stitches from the current row together with the same stitches several rows below. The number of the rows is usually double the number of the stitches – for example, if a tuck is 5 stitches, then you knit together with the stitches from 10 rows below.
