We have always gone in for alternative garden decoration, ever since we went to an Arts Centre in Knaresborough which had a lot of CDs on a wall. We just thought they looked nice and suspended some on a tree in our back garden but then discovered that on a sunny day if it is a bit windy they will cast beams of light round the garden, and give off a kaleidoscope of colours.
I have a butterfly light holder which contains a tealight for summer evenings. I bought this last year but never used it as it rained most of the summer so I hope I can get some use out of it this year as I suppose it will softly light the butterfly.
Mark's idea: curtain pole ends bought reduced for about £3 and made into interesting features. Also a Buddhist prayer flag (don't know what they make of this next door). We have been to a few Buddhist meetings and Mark used to try to meditate but never got the necessary peace in the house lol
