What is an action chart?
An Action chart is a What You See Is What You Do (WYSIWYD) chart.
Why use one?
If you have ever been confused by what stitch you are supposed to execute on the wrong side, this might be a charting system that works for you.
How to read an action chart?
The charts do not show what the right side of the knitting looks like when working flat, just what action you should take. The right side is always being worked when working in the round. (Note the way Seed and Stockinette differ in the round and flat.)
Whenever there are 3 or more of the same type of stitch in a row I use the colored boxes and specify how many stitches to work (k3, p3, etc.). This is to make it quick and easy to take in the information.
Pattern Specific Variations
Sometimes, I include technique variations that are for specific patterns. I always include directions for specific techniques in the pattern itself, so be sure to also read any patterns you’re working on closely.
