When knitting stranded colorwork (fairisle), it is often easier to knit in the round, always on the right side of the work. It is also easier to read the pattern if you always working in the same direction, knitting on the right side from right to left.
This is why the "steeking" technique was invented: to be able to knit in the round (in a tube) and to be able to create an opening (or openings) by cutting the knitting afterwards.
The following video tutorial shows you this technique from start to finish and you will also find under this video the written explanations with illustrations to learn how to prepare the steek before opening and how to cut the knitting!
STEP 1: To make a steek, we will normally increase 5 stitches at the location where the opening will be created later. These 5 stitches will then be cut in the center and are usually knitted by alternating the 2 colors of your colorwork. In the example below, our steek is composed of a blue, beige, blue (center), beige, blue stitches:
STEP 4: When both sides of the center stitch are secured, use a sharp pair of scissors for best precision and cut the middle of the center stitch (bottom up or top down doesn't matter, as long as you make sure to cut the center of the stitch).
STEP 5: Once you have cut the steek and opened the fabric, fold the remaining stitches of the steek inside the fabric and secure it with a piece of yarn and a tapestry needle.
Have fun working your steek: the technique may scare you the first time but you will see that it is very easy to do!
Happy Knitting!!
