Well finally got the fitted sheets from Duvalay sorted ( other sheet makers are available ),went to pick them up yesterday to save the postage,they are only about 20 minutes away but not the easiest place to find if you aren't using a sat-nav,they are only small,very small.
They fit very well ( better than they look in the photographs really ).
SWMBO didn't appreciate the colour I had picked as I thought I would surprise her.
She seemed to be of the opinion,strangely,that pale blue doesn't go with the green and maroon of the Duvalays.
Anyway after a bit of a "domestic" we are friends again.
