Two days ago, after much head scratching, scribbling and random counting I completed my first crochet patten!
This afternoon, while watching Sons of Anarchy, I tested it and it works. I've posted a pic of my skull granny square below.
I'm pretty proud of it and really enjoyed the process of creating it. I'm going to think about some other shapes and try and sketch things out I think.
At the moment the pattern is a combination of lines, circles and highlighter marks. As soon as its a but neater I will post it for you all to use.
