This pattern is quite easy. You only need to know how to work increases, follow a chart and sew an elastic (and my way of sewing an elastic is really easy).

You will need:
C1: 2 (2, 3, 3) skeins of Spring Green
C2: 1 skein of Violet Heather
C3: 1 skein of Ash Heather
C4: 1 skein of Dark Grey Heather

and also:
an elastic band 1’’ large, the same length as your high hips circumference
a tapestry needle
3 markers
sewing thread

Branka is the name of the girl in the novel I’m reading right now, Hollywood by Marc Séguin (he is a genius)
