That we find a crystal or a poppy beautiful means that we are less alone, that we are more deeply inserted into existence than the course of a single life would lead us to believe.
-John Berger

This is a pattern for a circular yoke jumper worked from the top down and using the Fair-Isle knitting technique. There are instructions for both a plain or motif sleeve. The plain sleeve has a basic sleeve shaping, the motif sleeve is a wider sleeve over the lower third of arm.
Since this is worked from the top down you may make small adjustments to size by adding more or fewer sts at underarm cast on.
