I am definitely having a real tree this year. We have a lovely big living room, so space isn't an issue, but we do have varnished floorboards and I don't want to spend 2011 picking up pine needles from the in between the boards. So, what can I put under the tree to 'collect' the needles? Needs to be Christmassy but not naff. Also something that I can gather up and shake outside when it becomes too full of needles. Can only think of an old sheet but that would look naff. Any ideas?
