If you are looking for a twist of the typical muffin cups, look at these Tulip baking cups. They are designed to fit the standard 2-inch muffin pans.
These four-petal cups are made of Swedish greaseproof white or brown paper. They come in three sizes. Make sure you get the tallest model (2 3/4) since it is the only one that form a uniform tulip shape. The smallest sizes are randomly folded. Plus, taller muffins look more sophisticated.
You may want to revisit my tall muffin presentation where I discussed how to make your own tubular muffins. The raffia string creates a modern rustic look. For a more stylish look, replace the raffia by a beautiful paper band hold in place with an elegant ribbon and a decorative button.
