Level Intermediate

Being asymmetrical, one side is larger than the other: it
starts from a larger circular shape and grows into a long,
curved tail that wears thin to the other end.

This particular form is obtained by increasing and
decreasing, to fit the shoulders and protect the back of
the head and the throat.

The Blackhole starts from the circular hole, knitting in
the round. After few rows, the hole opens and you go on
knitting in flat, going back and forth, to create the tail.

The tail is knitted in two parts on a provisional cast on.
It requires a single, central stitch seam.
