No, not there Hugo, you were nearer with your 1st answer.
I suppose it is rather obscure, but I have been trying to get a picture of it for a number of years, but it is not in an ideal place to hesitate.
It is on a house on the left side of the A495 between Barmouth and Dolgellau, just after the turn for the Penmanpool toll bridge ( which gets more wobbly every time we pay our 70p and cross it !)
Just out of interest, as we passed through the village of Llwyngwril I managed, as we crossed the bridge, to get a shot of this latest offering from their 'yarn bombing' activities. !
