There is some blue staining which is, presumably, coming from the flowers.
The flowers are starting to rot, which is putting some darker, murky colour onto the tapestry, I think. I am not sure if it will last if I ever decide to wash the tapestry. But it will be interesting to see.
There is still a month to go before I have to decide if I am going to enter it in the challenge. I'll wait and see what state it gets into by then.
