Knitting is a common hobby, mostly as an idle practice. It involves a repetitive motion of creating loops and knots in a series that ultimately forms a single piece. This motion is assisted by 2 rods where the piece is transferred at every change of direction. The pattern of the loops can be deliberate (purl stitch/knit stitch etc.) and alternate.
One can use unconventional materials to create knitted pieces. The pieces can also form unconventional shapes and even 3D forms. Here are some of my experimentation with raffia strings, cotton threads and conventional yarns.
