Yeah, the yon is yarn over. I've never seen it written like that before either, but the pattern is from a magazine, and they show you how to do it. :D I've only done the pattern once through (I did it twice before, saw the vertical stitch 'loops' at the back of the knitting and frogged it
) so maybe i'll give it another few 'cycles' before I give it up as 'A Bad Thing'. It wouldn't bother me if the pattern was for a jumper where the inside isn't so visible, but with a wrap/scarf, it might show, and it looks ugly.
Thanks for the reply.
