This is the Tulip Pattern from Barbara Walker’s A Treasury of Knitting Patterns.For those of you who are familiar with the collection, that’s the blue one or the first one. It’s on page 25 and is worked as follows:
Over a multiple of 3
Rows 1 and 3 (RS) – Knit
Rows 2 and 4 (WS) – Purl
Rows 5 and 7 – K1, * p1, k2; rep from *, end p1, k1.
Rows 6 and 8 – P1, *k1, ps; rep from *, end k1, p1.
Rows 9 and 11 – *P2, k1; rep from *.
Rows 10 and 12 – *P1, k2; rep from *.
And it looks like this:
It’s not super stretchy so it won’t nip in like straight up ribbing does, but has a combination of knit and purl stitches that makes it lie flat. It gives a bit of textural interest to an otherwise plain stockinette fabric, or is subtle enough not to draw too much attention on something more complex. It could also be used as an all over fabric. The example you’re looking at is still on the needles, but I’m thinking it will flatten out a bit with washing and blocking. All in all, a sweet edge treatment.
