It took an age because it started life as this.....
.....and I unpicked it after putting up with those e-NOR-mous sleeves for far too long.
When I'd originally made it a hundred years ago, I'd sewn up the seems so well that I could hardly see my stitches. That's why it's lasted so long but it was sooo tedious to try to unpick let me tell you! Anyway the task is done, it fits me and is thick and warm ready for next winter.
Next winter? Yes, because you might have noticed how warm it was today - Spring is Springing!
