This Vest In Show Argyle Affair Vest pattern uses intarsia technique on the front to work the argyle diamonds and diagonal lines. The back is worked in stripes.

The pattern instructions are mainly a chart. There are 6 different sizes so 6 different charts. The knitting charts are separate PDFs of the different sizes and are on the Ravelry download page. Each chart gives you the possibility to color in your own color choices.

I added Woolen Affair Vest_Size 0_FINAL which is a chart, the largest size, that has extended argyle diamonds and diagonals so that you can more easily adjust the pattern to make it wider or taller.
