What you could do it to unpick your cast off end, and unravel back four or five inches. Then put half the stitches onto a safety pin (or thread through a bit of string and tie in a loop) and knit back a couple of inches of length on the other half stitches. Put those ones onto another safety pin or loop, and knit the first set you pinned off back up to the same length. So you have two short 'straps'.
Now, put both sets of stitches back onto one needle and knit them together again to the end.
Cast off.
You've now made a slit that you can pull the other end of the scarf through so that it sits snuggly round your neck and will cover the bit where your jacket comes up to your throat.
