Why do I add a stitch when knitting?
An “accidental yarn over” occurs when you bring your yarn to the front of the work (as opposed to keeping it in the back). Then, when you go to knit the next stitch, the working yarn goes up and over your needle creating an extra loop on your needle as it makes that next stitch. This will also create an extra stitch.
How do you increase one stitch in the middle of a row?
At position of increase,insert right-hand needle into top loop of stitch on row below next stitch on left hand needles. Knit an extra stitch through this stitch then knit the next stitch on the left-hand needle.
How do you increase stitches at the beginning and end of a row?
One of the easiest ways to increase is at the beginning of a row. Insert the right-hand needle into the first stitch as if you were going to knit it, but before dropping the stitch off the left-hand needle use the tip of the right-hand needle to place the new stitch onto the left-hand needle.
