From pattern description:

This oversized V-necked sweater is a chunky update of a traditional Argyle design. The geometric diamond patterning, followed from a chart, is a good first intarsia project as the patterning repeats across the row. The back is kept plain and simple for maximum contrast, but if you wish to continue the patterned border to the back, just follow the instructions for the front to the armhole shaping and double the amount of color A and B yarns required.

Other Materials:

• Super chunky wool yarn: Color A - 30 (39) oz; Color B - 3 (4) oz; Color C - 3 (4) oz
• Tapestry needle
• 16 (20) bobbins

Finished measurements:

Back length 26 3/4 (29 1/2) in.
Chest at underarm 50 (54) in.
Sleeve seam length 19 3/4 (21) in.
