S is for Something Blue

It don't get bluer than this, I can't remember where I picked this up, some evening train-fair in a school hall probably! But a fascinating 'artifactal' thing nonetheless.

It is basically crêpe plastic! A sheet of shopping-bag type polyethylene has been run though the paper crêpeing [spellcheck says 'crêpey'!] machine (interlocking-rollers?), probably with some heat in the mix, and when cooled you have a brilliant water surface for model railways, that glistens like you want to dive-in!

'Something borrowed' later today!
