I-cord makes a stretchy and effective edging to a shawl, especially when it carries on from an i-cord edge along one side of said shawl. I use this bind off in my Samhain shawl/cowl, and I like the way it curves around to blunt and shape the corner of the shawl. Samhain is a double-layered accessory and for the cast off, in order to avoid flaring, the two layers are treated as one.
This is how it is worked
Knit the first two i-cord edge stitches, slip the third i-cord edge stitch knitwise
The three i-cord edge stitches are now on the RH needle. The next stitch is a knit, so I will slip that also knitwise.
The third i-cord edge stitch and the first (knit) stitch have been knitted together through the back loop – a standard ssk
Pass the three stitches from RH to LH needle without twisting them
Knit the first two i-cord edge stitches again, slip the third knitwise, then treating the next two stitches as one unit, slip them also knitwise
Knit the three slipped stitches together through the back loop
The three stitches on the RH needle are now the i-cord cast off, and the curve of the corner is already evident
Pass the three i-cord stitches back to the LH needle
A few more stitches cast off and the corner has taken shape with a smooth curve
