I’m still here. I took my laptop to a computer shop on Tuesday. I collected it yesterday and..... It was the same as ever. So I took it back to the repair shop this morning.
I’ve just finished a pair of helix socks with afterthought heels. They came out well. I had to unlearn my habit of crossing threads when changing colours. Looking at the work thoughtfully I can see why it’s not necessary to cross threads. The yarn is carried from one section to the next. But I hadn’t realized that crossing threads would result in the jog I was trying to avoid. I’ll put some pictures up when I can. I came across helix hat and socks on Pinterest, so look it up there if you’re interested.
