This is my go-to charting software and being actively developed and updated.
…and the Stitch Mastery love grows….here’s a tiny example of how the program can hide edge stitches (instead of knitters having to print all those grey ‘no stitches’); the key is editable; you can create your own stitch libraries (plural!); it generates written directions; understands repeats within a chart; the underlying structure is based on CSS so it’s very customizable; you can have the stitch definitions show along with the abbreviations; key can be exported as individual stitches, if desired; the list just goes on and on.
