Christmas mantelpiece

The house is gradually getting ‘Chrismasified’. This is my mantelpiece, which could do with more tealights lit. I put the tree up today today, a Nordman fir, but I am such a fuss pot, I am not altogether happy with the lights and some of the decorations have already slid off the branches without a cat in sight! :(
I shall have to adjust and fortify it tomorrow!
