This shawl is made in tiers of Entrelac with each tier containing one more stitch per row and one more row per block. Every tier begins at the same starting edge. This is similar to the Curved Entrelac Scarf which has only 3 columns. The shawl is made with 4 columns and can be made wider using 5 or 6 columns.
The shawl is about 60 inches along the outer curve and 18 inches deep at the widest part.
The Grey Skies shawl uses only 2 colours, the Tulip Fields shawl uses 6 colours. Make a swatch of 15 stitches x 15 rows to determine the amount of yarn for the largest blocks if you are using leftover yarns.
