The colours are modern for this take on a classic design from decades ago.
The pattern includes a crochet diagram for the square and how to build it to shape the top.
There is also a fashion schematic for sizing and more.
For those who enjoy making crochet clothing, we have another choice you may be interested in. The Zig Zag Top Overlay may be in your wheelhouse for styling and design. The free pattern includes a tutorial too.
