Maybe the skull graph was the first intarsia crochet that I ever did. It was definitely the first design that I put on a graph, and the only one that was sold as a pattern. It’s very old, and it’s very awesome. I’m redoing the entire thing and re-releasing the pattern… including the graph and instructions on how to make a 12 X 12 pillow and some talk about the different ways the graph can be used (including for knitters, weavers, and bead slingers).
I use this technique All. Of. The. Time. I hate raw edges on my crochet work and tend to turn the work to make different shapes. When writing up crochet patterns that use this technique (most of them), I’ve been taking pictures of how to do this, like it was a weird thing to do when crocheting. It dawned on me that this is a basic crochet skill that we should have in our arsenal of awesome crochet tools.
