Happy St.Patrick's Day

This morning I finished my first Pi sick. Knitting goes fast in thick yarn. 

So from left to right are the numbers of Pi represented by number of row in alternating colors. 

So

3 rows of dark green 

1 of the lighter green 

 Continuing on 4159292653589793. The toe isn't included. 

I have plenty of yarn left but I am thinking of switching the starting color from dark green to light just to mix it up
