I'm fascinated by Iilla Bjorn's Blog. Although I don't do much crochet,
she has been inspiration to pick up the hook and try it again.
Iilla has this interesting blog post about charting for crochet design
Here is one of the charts
And the key to the design elements
Here is how it would look in yarn. I love working with charts for my knitting so
now I can find charts for crochet and keep up with the work easily
