A knit bobble is a small bit of raised fabric that adds three dimensional texture to your knitting.
They are created by working a handful of stitches multiple times. This creates extra fabric in the spot being worked, which shapes the bobble, making it stand off your knit fabric.
Many knitters find working bobbles to be cumbersome because they involve turning your work many times. Backwards knitting makes working bobbles far less cumbersome.
