Add a festive touch to a nautical-themed birthday party by making a starfish garland.
All you need to create this decoration, which you can hang on the window, railing, or above the door, is twine and starfish. You can find starfish online or at most craft shops. To make this garland, cut a piece of twine to the desired length. Make a loop on each side to hang. Then cut shorter pieces of twine about 4 to 5 inches in length.
