I did a couple of swatches to figure out the edging of the scarf. I tried both random bobbles and the little sock heels I talked about yesterday. In the picture the bobbles are on the bottom and the sock heels are on top.
The bobbles are not quite what I was thinking of but neither are the sock heels. But I do like the look of the sock heels. They would make an interesting bottom to a scarf and they do make the uneven edge I was looking for.
If I use sock heels on the edge of my scarf I will have to cast on many more stitches than will end up as the body of the scarf. I think I have many swatches ahead of me.
