Today the Knot Won

With a few spare minutes to stitch this morning, I wanted to work on my fishy tea towel, a Mary Corbet design. I find it relaxing to choose different colours and stitches as I go along.

When the thread seemed to snag, I turned it over to find a nasty big knot! 

The question is, how long do you try to untangle it for? I spent ages carefully trying to prise the knot open and straighten out the thread. But, today the knot won!

I shall have to cut the thread and unpick. Fortunately there's not a lot to undo.
