This tutorial explains a technique use in my Hecate (Ravelry link) shawl from Issue 26 of Pom Pom Quarterly but I’m sure that you’ll find it handy for any shawl with an i-cord edge that begins at the corner.
The corner i-cord tab, is fairly similar to the straight i-cord tab cast-on, as featured in my Ama shawl (Ravelry link) except that a yarnover is worked in the middle of the picked up stitches to create the corner.
First work the i-cord as instructed in your pattern, here I’ve worked six rows to create six ‘v’s in the i-cord (worked in the dark grey yarn, the rest of the tutorial is worked in light grey to make the technique clearer, but you can follow your pattern).
When you work the next row, don’t slip the stitches back to the left-hand needle, but turn the work 90 degrees clockwise to pick-up stitches along the edge of the i-cord (if you’d like help with picking up stitches along an i-cord, see my handy tutorial here).
Skip the ‘v’ directly underneath the needle (the first dark grey one in this example), and pick-up one stitch in the next ‘v’ by inserting the right-hand needle under both strands of the ‘v’, looping the yarn around the needle and pulling a loop through. For this tutorial, I’ve done this twice (which is different from the Hecate pattern to protect copyright), but your pattern will advise on how many stitches to pick up.
Now we have reached the middle of the tab, make a yarnover (this enables the tab to bend and creates the point or the corner of the shawl).
Skip the next ‘v’, and pick-up two stitches (or however many your pattern says) in the following two ‘v’s. There should be one ‘v’ left, which we will skip.
Finally, turn the work 90 degrees clockwise and pick-up three stitches from the cast-on edge. Work the wrong side row as per your pattern.
Yay – you have now worked an i-cord corner tab!
