I LOVE that wreath, and I totally want to do something similar. Not sure if I can get it done this winter or not since I am having a little one on the 16th of December and we are always busy, busy this time of year. I'm thinking I might have to make an easter or valentine's day wreath though if not.
I too have used pine branches and pine cone to make natural and inexpensive decorations. Also, just putting up all the old Christmas photos in the picture frames you already have really helps change the mood and lift your holiday spirits. This year I made a tree on our wall with paper plates. I didn't want to mess with a tree, plus I am slowly making/buying special ornaments since we have so few. My daughter loves it, and it takes up so much less space in the small living room we have (and dd can play with it without me worrying about anything breaking, a whole tree coming down, etc.). The tree cost me a whole three or four dollars, since I also bought a bow to tack to the top.
I'm going to be making some of those snowflakes tonight actually!
I took some leftover ribbons from the craft box and strung them up on an empty hallway wall we had. Just an extra bit of festivity.
Really, this whole Christmas season has been very inexpensive.
