It's just a little inkle band, this one made with 5/2 pearl cotton for the warp, and 3/2 pearl cotton for the weft. These sure do weave up fast, as it was warped one evening, and woven another, while watching TV.
On my loom now:
It's sock yarn on it's way to becoming a scarf. I'm still a beginner weaver, and sock yarn seems to be more difficult for me to get acceptable selvedges than non-stretchy cotton or linen. While I know many would have this done in a few hours, it will be here a while, as I only work on it between other projects.
