Translate a Cross Stitch Chart's Symbols Into a Plain Stitch by Stitch Guide

The symbol key has fourteen near identical shapes and you have already unpicked one section twice. This is for stitchers who can sew but lose time squinting at charts. You get every symbol translated against colour and stitch, the fiddly stitches explained properly, and a sensible order to work in.
