My friend Su has a wonderful sense of fun, even when she is serious. if you click on the link you will find a selection of goods to buy at very little cost, proceeds of which will go to her chosen bowel cancer research/awareness charity.
I love the birdy badges - a wonderful school or brownie project perhaps? If you want to know more, use the etsy site and contact her through there. She has other, non-charity items too, which are wonderful and magical!
