I was about to suggest the same thing as t'other Anne, Otis, although it's not a pattern I recognise (yet!)
I'm not totally sure of the colour - a flat white background is better if you can manage it as then we can see the colour more accurately - even a couple of large sheets of paper beneath and behind it will do the trick, or as I do sometimes, use the white tiled wall in the kitchen!
It looks more yellow than amber ... would that be right?
