I know it's out there, but I just can't seem to find it again. It's on a site that has other free patterns. Please, I think someone even provided a link to this website in these forums somewhere, but it still eludes me. Here' how I would describe it:
The picture I saw was not a garment of anything, but I think it was kind of like a swatch just to show the design. The yarn colour looked like a beige-brown. The pattern looked like imperfect seashells or seaweed. It was just the raised outline over stockinette.
Please, please, please, if you know what I'm talking about, add your comments to the thread. I would really love to find it again.
