I made this Advent calendar last year for my son:
As you can no doubt see, it's made from glittery green felt, some burnt orange fabric, some tartan ribbon, deep red felt, white felt for the numbers, bits of sparkly gold thread and some white buttons.
I'm certainly no sewing expert and have to say, I was quite pleased with the finished result. The decorations are made from Fimo. You can just see Father Christmas hanging at the bottom. I'll do another post when the tree's fully decorated in a few weeks!
