Boring Bobbin

I have no idea what this is, but it sure was fun! It came in a sheet much like quilt batting. It is mostly brown with random flecks of red and green. It was also very greasy. Yuck! When I spun it up, it reminded me of candle wicking. I wound it in a hank, dropped it in very hot water with euglena and crossed my fingers. When I pulled it out, it was lofty and soooo soft. I cannot get a picture that shows how beautiful it is. But what do I with around 2 oz. of yarn? Use it for trimming on something else? Wait to get a ton of these random little hanks and so a patchwork something? Help!
