Vell, dullinks ...
I managed to create my two lots of PCO at either end; but I can tell you that it took me most of the afternoon to work out how to get them in the right position to enable me to knit the last three sts of one lot and then go back to start knitting on the WS.
I reckon I swapped all those ****ing stitches from one needle to another roughly ten times before I got 'em into the position that enabled me to proceed. Talk about Alice falling down the rabbit hole! - I thought I was going to continue swapping those sts for the rest of me days.
But I am now on my way with this first half. When I get to the second half, the scales may fall from my eyes and all will be clear.
Don't hold yer breath but.
