This shawl is worked with a classic top down construction technique. It starts from a small garter stitch strip of knitting. If you are new to this technique I have a blog post with more detail here. The lace pattern is created with stacked hearts. They end with eyelets which create a scalloped bottom edge. The entire shawl is charted. It can be made larger easily by repeating Charts 3 and 4 any number of times before completing the final chart for the border.
