This year I was looking for some simple chic windows decorations. Cut paper snowflakes seem to be perfect if you don't want to buy new decorations but also want something new. As a child we used to cut these stars at kindergarden. You can use golden and silver foil as well. Here's a little pic and DIY from Jelene.
Christmas decoration is always a challenge. Of course you can buy a whole deco concept but I think especially for christmas you have to make something on your own. It's the season to be crafty. And it's cheap.
