This is your regular solid granny square made with double crochet. This is charted on a grid paper where every square equals 2 double crochets.

The pattern includes a chart created on Stitch fiddle but that is merely to help follow the written pattern.

The square uses 5 colours and each colour is carried across the back and worked over when not needed.

MC(barley) - 140 yds
CA(red) - 40 yds
