I did my braiding/weaving rug course last weekend online with Ilke White. I am using a favourite old chartreuse T-shirt, navy camisole and tights, and plaid PJs so far. Almost any type of material can work. I may add in some other neutrals to make the colours pop more. Not sure how big I will make this round rug yet. Found the math a little hard to understand, keeping the working loop of your rug at a 45 degree angle is critical. Still learning as I go. Next time I think I will try the oval rug option. It’s a great way to use up old material scraps and to preserve those favourite old clothes you’ve been hanging on to that are too tattered to donate with dignity. Will post again when I finish this braided baby.
