Border for Pinwheel Blanket

I am knitting the round or pinwheel blanket from Knitlist and am considering borders. Would an I-cord bind off be sufficient? I think it would look nice but not sure it would hold the stockinette from curling. I am making it out of stash woolease and don’t think blocking will make a huge difference. If you have made this blanket, what border did you use?

The pattern:

I just did a garter border.

Anyone else?

Some suggestions in this thread on that same topic.

Lots of Pics of finished ones here for more ideas. Quite a few seem to have ruffles as edges.
