The Knotted Openwork stitch is a multiple of 3. Four rows repeated form the pattern. Enjoy!

The Waterfall stitch pattern is a multiple of 6 + 3. Six rows repeated for the pattern. Enjoy!

Each month I post a knit stitch for you to try your hand at. To try each stitch, start with two rows of knit 1, purl one ribbing as a foundation. You may also want to add a couple of edge stitches at the beginning and end of your test swatch. This could be knitting two stitches at both the beginning and end of each row. This will prevent the fabric from rolling. Then begin with the stitch directions for each specific stitch. Keep in mind the multiple of stitches and the number of rows to repeat to form each stitch, when casting on your stitches. If you begin your swatch with two foundation K1, P1 ribbing rows, you will want to end this way as well.
