Calling all BookCrossing Supporters

I've managed to get hold of a space for a BookCrossing Xmas Tree at my local Community Christmas Tree Festival. Loads of local businesses and organisations will be decorating trees to advertise what they do. Since BookCrossing is such a part of my life, I felt it was important it had a place in the community as well.
The festival is raising funds for the Oxford Night Shelter, so its all in a good cause.

I need your help though. To do this I need to have enough decorations related to BookCrossing (for instance bookmarks, covers of your favourite books, pictures of places you might release a book etc) or Christmas to fill a tree. I'm going to make some myself, but I wondered whether anyone would be willing to send me something to add, so that it really can be full without me collapsing from exhausted.

I'm also looking to do a sort of 'BookCrossing Treasure Hunt', wild releasing books around the venue that are related to Christmas Tree, decorations or the Christmas Story. If anyone has a suitable book they're willing to donate please let me know.

We will be setting up on Friday 9th December, so there's not long to go.
If you're able to help in any way please leave contact details in the comments (also the place to ask any questions you may have).
Thanks very much.
