Shaping the top
Shaping the top of the tea cosy pieces proved to be easy after all the struggles so far. It just required a couple of rows of decrease stitches. Having said that, the last instruction seemed a little opaque to a beginner like me:
Break off yarn, thread through rem sts. Pull up tightly and fasten off.
I understood it all except the “fasten off” part. Fasten off how? Tie a knot in it? It would run straight through the remaining stitches I’d just pulled it through. I had no idea. I asked the internet for help. The answer I got was perhaps obvious: sew in the end with a darning needle to hold it in place. I did that, and it seemed to work.
