So here are a few pictures of how my infinity scarf turned out using the largest (yellow) knifty knitter hoop. It was pretty simple. I pretty much just made a large "brim" like you would make for the hats. Stretched out it's about 11 inches wide. Not stretched it's about 6 inches.

It's a green/blue/tan color. Very soft and kind of stretchy.
