A fringe border can be made by dropping stitches along the border from the top to bottom of the knitted fabric. This is the same as producing a vertical stripe in drop-stitch knitting.
A common method for producing one or more loops is as follows. The yarn is formed into the desired number of loops with the desired length. These loop(s) are held behind the work, drawn through the desired stitch using the right-hand needle and placed on the left-hand needle next to the desired stitch. The loops and the desired stitch are knit together to secure the loops.
Another method for producing a dangling loop is to knit twice into the same stitch, leaving a long loop in between; the two stitches are knit together to secure the loop.
