The ridge check stitch is a mosaic colorwork stitch. By pulling up a stitch of one color over a row with another color, a checkerboard effect is created.
The Slip Stitch Crosses Stitch is a pretty color work stitch that combines both slipped stitches and cables to get its undulating pattern on the fabric’s surface. The all-over pattern that it creates would work nicely for a bag, mittens, or a hat.
