To create this vest in less than an hour, you use two measurements to draft a circle and then just cut fabric and the armholes and bind the edges.
For a super-comfy version, choose a thick fabric such as fleece. For a more sweater-like creation, choose a loose knit. Finish the raw edges with strips of ribbed knit; you can shape the knit easily around the curved edges, and it stretches to fit. For a quicker no-sew version, make the vest out of fleece and cut the edges with pinking shears. For a double-sided option, topstitch two layers of fleece together.
Whether you make it in a lightweight fabric or in a cozy knit, this vest is the perfect addition to any wardrobe regardless of the season.
Draft and sew the vest
Start with your measurements to draft the vest pattern, and bind the edges with a coordinating rib knit.
1. Draft the pattern. Measure your bust circumference. Draw a circle with this measurement as the circle's diameter.
2. Measure for the armholes. Measure across your back from arm to arm to determine how far apart to make the armholes. Determine the armhole depth by measuring from the top of your shoulder to about 3 inches below your armpit.
3. Draw the armholes. Center the armholes vertically on your pattern and mark them your back width apart (as determined in step 2).
