garter stitch scarf

[amala]

i'm looking to make a scarf that i've seen in stores. it's like a tube. you can put your arm all the way through it but you wear it like a normal scarf. i have an idea of how to make it but don't know what it's called or how to find a pattern for one.

and thoughts?

happy thanksgiving!!!

oh yeah, preferable using circs. i don't have dpn's. yet.
