Steeking means to cut in norwegian. I love this technique for Fair Isle. Here is my example of steeking using the Mossbank design from a Jamieson Shetland Knitting book. I love this technique for knitting vests and sweater in the round (tube). You cut between the 5th and 6th steek sts after completing the project to open the tube and then usually pick up stitches to add a border. This is especially useful in fair isle, to avoid having to purl stitches while carrying your yarn. The white thread I inserted along the edge stitches to mark my steeks for the photo. I prefer ten stitches for my steeks. Don't be afraid to cut your knitting!
