make use of things that you like such as color paper, buntings, wall hanging materials, balloons and whatever you have in the house, what you can get from thr market and make yourself.. the idea behind it is to be creative and bring your creative side out.. go for what you like.. and how you will like to make your home stand apart from the standard christmas decorations this year...good luck
