Many thanks Craftybear, oh dear, this may be more serious than I thought, I have not seen any of the fabric sheets you mention here in New Zealand but I shall check out the super market more closely next visit, I am going to get hubby to look into all the techno stuff for me, we do get surges here and complete blackouts due to high winds and ice and snow at certain times of the year, better to be protected in the correct way!
