Knitting Increase Stitches
There are two ways of increasing stitches other than casting on. These are by knitting into the front and back of the next stitch or by ‘making one’. When you increase by knitting into the front and back of a stitch, you are left with a small bar across on the knit side of the fabric. This is barely visible, even with stocking stitch, but to increase invisibly, use Make One increasing.
Decreasing Stitches in Knitting
The following videos show two different ways of decreasing stitches for shaping. The slip one, knit one, pass slipped stitch over (skpsso in patterns) is used for a left slanting decrease, normally on the right edge of a garment while the knit two together (k2tog in patterns) is used for a right slanting decrease on the left edge.
