We have had the same stuff up on our mantlepiece, more or less, since we moved into our house eighteen months ago. Since we don't have room for a tree, I decided to decorate it for Christmas. I had so much fun I think I will try to do this regularly, and post photos.
The bunting was really fun and easy to make. I was inspired by Heart Handmade's Wee Bunting, and I enjoyed it so much I made extra for my office! Using felt to back the pieces is a good idea, because it gives the bunting enough weight and stiffness to hang properly. I didn't worry about getting the pieces the same size or even nice neat triangles, and I think it looks much better that way.
