Mitered scarf edge

Hello Everyone!
What a wonderful forum! So happy I found it! Ok, here’s my question. I am knitting a wonderful lace scarf, and decided that a nice ribbed edging would be nice, but I don’t seem to be able to find info on doing a mitered corner to go around. Any help would be greatly appreciated!

Wow… I can’t believe this has gone unanswered for almost two weeks! I’m soooo sorry!

For a mitered corner, I would increase 2 stitches (KPK in one stitch) at the corners every other row. Try to keep in pattern as best you can. When you’re improvizing a pattern as you are, you really need to just kinda wing it and do what you think looks best. Good luck!
