You will be crocheting the back panel of the vest in one piece, bottom up.
Next, you will block the panel to 16″ width by 23″ length.
Next, you will add two sides at the bottom of the vest by joining yarn & working rows outward at the lower edges.
Lastly, you will add a border to create the armholes.
(You can also optionally add tassels or fringe at the bottom once complete)
