sEWING IN A SHAWL COLLAR

I am wracking my brains! on how to sew in a shawl collar in a knitted jumper, try as I might the instructions don’t make sense and I can’t find a how to knitting video to show me, which would be better for me.

Jenni :??

More info is always better. Can you please give us the name of the pattern and a link if possible?
