About half a century ago, someone sent my children a clear glass star (each) for the christmas tree. From then on, every year I bought some more clear glass ornaments for the tree. Icicles, angels, birds... IKEA often had them.. Back then, antique lead crystal drops from old chandeliers, went for pennies in junk shops and jumbles. Yet another collection of cheap treasure was born..all hung on the tree every christmas then wrapped and put away.
By the time all the kids had grown and flown I'd accumulated scores of these clear glass and crystal shiny danglers; we moved house and acquired a huge bay window. For our first Christmas in new home, instead of decorating a tree, I painted two white broom handles, fixed them across the bay window and suspended all the glass and crystals from them on different lengths of invisible thread. It was so absolutely gorgeous I never took them down.... still twinkling in the sun and casting rainbows round the room all year round , 5 years later.
Christmas is now relaxed and effortless, no tree, decs always "up" and the children have taken over all the hosting.
