Little ribs on the outside and big ribs in the center, so you get a nice drapey stockinettey scarf with no curling up on the edges.
Scarf pictured used 2 skeins Sunday Knits sport-weight yarns, with 225 meters/50-gram skein. If using another yarn, 3 skeins may be needed for this length.
The pattern is too simple to take up a whole pdf - it’s just a couple of lines, and they’re free. Just go to my web designs page, link to scarves and shawls, and scroll to the bottom.
