This multi-page knitting pattern, complete with photographs, provides detailed instructions to create a medium size vest for women who wear size 6-8 tops. The Betty Martin stitch design provides a classic and traditional Aran look. The beauty of the Betty Martin stitch is that it creates separate beautiful patterns on both sides of the vest, making it fully reversible (and impossible to decide which side to wear). By stitching four buttons on each side, you can wear it using the side you prefer on any given day. The vest in this pattern was made with a light fingering weight yarn. While it takes a bit longer to make the vest due to an increased stitch count, the detail is enhanced making both sides stand out with distinctive and well-defined patterns.
