I'm reasonably sure I can handle it, but it's more complicated than I really wanted at present. Still, I may as well continue now I've started. Hopefully it'll get easier as I get used to the various patterns. I do wish my needles were a bit pointier for the blackberry stitch though. Purling three together is difficult with the blunt pair I'm using. Might have to switch to a better pair.

I'm mystified too. Maybe the pattern writers are counting the blackberry stitch as pattern 1, who knows? Cabling on the right rows will be a challenge since the two cable patterns twist on different rows, and in different ways o_O I've done more complicated patterns, but not working from several charts.
