These are the most complex samples I did from my Craftsy cable class. It takes a lot of concentration and attention to detail to keep from screwing up on these. I used the Good Notes app on my iPad to color code the chart for the celtic cable on the right. I don't think I could have done it without doing that. I want to try the whole sweater but I'm worried I'll screw up and pack it in. I'll just have to get over these self doubts! Here's the picture of the color coded chart.
