I have a cute little 4ft Christmas tree in my bedroom, all higgledy piggledy with mismatched decorations from everywhere.
My decorations are mostly from Paperchase, Homebase, Wilkos, and Accessorize over the years, with a few from other places. Including a couple of homemade ones.
There's no theme and most of the decorations are... less than traditional.
But I wouldn't have it any other way.
