When I saw what Shwin & Shwin did with a recycled T-Shirt, I was thrilled! I have 3 such T-shirts that met their doom while accidentally being dried on hell setting in my dryer. So I decided to grab my scissors and cut the first one up to see how it went.
As you can see, my loops are a tad tighter than Shwin & Shwin's. Also, I only got 13 rings, instead of the 16 they got - so my scarf is a tad shorter with tighter rings. I think I will make the rings much looser with the next T-shirt.
Here I double wound it to make it a cowl. I really like it as a cowl.
