To make it easy to follow, let’s start from the front part of the house, so Christmas front door decorations will be first thing to be discussed. Make a warm welcome to your guest in cold December by put some Christmas related decoration there. That is the entrance of your house where people go in and out, so don’t put decorations that can hinder or obstruct the movement across the door, like Christmas tree, table, and so on. Putting some sticker or hanging decorations in both outer and inner side of the door will be great idea. Then move to the guest room, nah, now you can place Christmas tree, but once again don’t put them in the area where people move to and fro. Place them in each corner of the room or right in the middle. For the middle placement, use a small Christmas tree instead of big one, so it won’t impede the people’s sight and interaction.
