Green painters masking tape / or Washi tape
Washi or Blu-tack to attach decorations.
This year we won't be at home for Christmas so I didn't want to buy a tradition tree and have all the needles fall out all over the carpet while we are away. Also it's really difficult to get rid of a christmas tree when you live in the city.
Moo decorated with existing decorations plus some cute mini christmas present decorations.
Which we made from empty raisin boxes and some curling ribbon. Moo loved these!
