I just happened to find myself in the vicinity of Hilltop Yarn yesterday so I just had to stop by since I haven’t been there for a while.
A few Jo Sharp sweater samples were on display. I was immediately drawn to the stitch pattern on a sweater called Tundra which is in her first book. She has given it the indistinct name of “rib texture pattern”. I haven’t come across it in any of the various stitch books so I don’t know if it has a common name.
Yarn: Jo Sharp DK Wool (KR review)
Color: 507 Miro
Needle Size: 6
Gauge: 4 inch square = 25sts and 30 rows
* = pattern repeat ( 3 stitches + 1)
Row 1: k1, *knit next stitch but leave it on the left needle instead of dropping it, bring yarn forward between needles and purl next two stitches on left needle, take yarn back between needle and knit next stitch*. Basically the second stitch is worked twice, first it is knit without dropping it from the left needle and then purled with the third stitch.
Row 2: purl each stitch if working flat or knit each stitch if working in the round.
Here’s a clearer picture worked up on the same needles in a lighter colored worsted weight yarn called Cascade 220.
Update: The 365 Knitting Stitches a Year Perpetual Calendar list this stitch as Supple Rib.
