Tiptoe Through the Tulips
Description from Knitty.com:
S, M: 30 sts/40 rows = 4" in stockinette stitch on smaller needles
L: 28 sts/40 rows = 4" in stockinette stitch on larger needles
With a stripe pattern that seems random [but isn't] and intarsia on the heel, these socks are designed to get you back into sandals as soon as possible [I like socks with Birkenstocks; sue me].
