I’ve finished the jumper and after washing it most of the crinkles have gone.
It took hardly any time at all to sew it up and there were very few ends to weave in. I remembered not to cut the yarn when I’d knitted each stripe and carried the yarn up the edge, knitting it in as I went. Usually I forget to do that and end up with a load more finishing off to do.
Now, what shall I knit next?
