Knitting chart symbols
A symbol describes the stitch as seen from the right side; wrong-side rows often require the opposite physical stitch.
Work the technique
For the chart studio key, an empty square means knit on RS/purl on WS; a dot means purl on RS/knit on WS; a circle means yarn-over; / means k2tog and \ means ssk on the RS. Read the chart key for any pattern you use.
Try it on a sample
Chart a 6 × 6 seed-stitch sample. Read RS rows right to left and WS rows left to right when knitting flat.
Check and recover
In the round every round reads from the same edge. A shaded no-stitch square is not a stitch: skip it when a shaping chart changes width.
