Weaving, knitting, and crocheting are all wonderful ways to express your creative abilities. Working with color and texture stimulate new neuron growth in your brain. While you are figuring out a pattern, your math mind (parietal lobe) is hard at work. As you figure out how to fix a problem, you are working your problem solving (frontal lobe) part of your brain. When you share ideas and compare projects you are building relationships which many studies have shown to increase brain function as we age.
So if you are a fiber artist already, knit, weave, and crochet on. If you are ready to learn, now is the time to learn. Give your brain a boost on yarn!
