This pattern is worked flat, in rows, and is worked up as 4
separate panels.

The panels are slip stitched together at the two shoulder edges to
create a cold shoulder design.

The bottom stripe edging is worked from the bottom cast on edge down.

Working in small panels means that this top works up pretty quickly.
It took me and my pattern testers between 16 and 18 hours to make.

That was working different sizes and with different skill levels.
