Simple Eyelet (multiple of 4 sts plus 3)
Note: the instructions below are a generic description of how to execute this stitch pattern. For a single repeat, you'd only need seven stitches but you'd have a VERY narrow piece! In the example shown, there are six repeats of the stitch, so to make a swatch that looks like the one shown, you need to cast on 27 stitches (6 x the multiple of 4 stitches needed for a single repeat of the pattern plus the three extra stitches.)
