Fat quarters are just an easy way to buy/sell lots of different types of fabrics, as they are a smaller cut than a full width of fabric. For a quilter, it means you can build up your 'stash' or buy heaps of different pattens to make up a quilt without having a heap left over.

If you are looking for ideas other than quilts for what to do with them, try googling "Fat quarter projects" The 'sew mama sew' blog has a heap of ideas for using the smaller cuts of fabric. I'm not going to look as I don't need any more projects at the moment!!!

Otherwise the "moda bake shop" is another good stop for little projects with quilting cottons.
