I have just been to the shop and have taken some pictures of the lights on the way. Today I took some pics of decorations on my dogwalk. These are not the most OTT decorations round here, but the more tasteful ones. The OTT ones are sadly totally outrageous.
I really love the little twinkly fairy lights in trees and bushes. The best ones are the white ones, and some have a really subtle twinkle, owing to the electronics, I suppose. However, I have posted a red one, as the white ones didn't come out very well (too subtle to photograph well, at least on my camera). It makes walking in the evening quite a magical experience, lots of twinkly fairy bushes and trees.
I also like these little flower lights, and I have taken a picture in the daytime (when they still look pretty good) and at night. I suppose my ideal Christmas garden would be lots of white twinkly lights in the bushes and trees, with a few of these flower lights. I think the pic I have posted with the lights of different colours is overgilding the lily somewhat, but maybe that's just me.
Also a Father Christmas climbing up the house, and you get a lot of those round here, and a few icicle lights hanging down from the roof, though those are rather passe, not like the cutting edge twinkle lights.
