Hey, that's just what the stitch pattern was called in the book.
By Eve Self
Using MC, CO 35
Row 1: using MC K1, *sl 1 purlwise, K2; rep from * to last stitch K1
Row 2: K
Row 3: using CC K1, *
Row 4: K
Repeat these 4 rows until scarf is desired length. BO using MC.
The only problem I had was when I moved on to my next project. After so many hundreds of repeats of slipping p-wise while making the scarf I found myself forgetting to actually make my purl stitches when I started something else! Oops...
