The simple answer is you don't NEED one. The view outside the window is often such a beautiful scene that it would be a shame to cover it. However not everywhere has such a view, or you may be in a Marina where the neighbours can peer into your boat at any time. You may want to add a little colour to your boat, or honour a treasure pet. Whatever your reasons, we have something to make you smile, including Christmas and Remembrance Day clings.
