A funnel that includes at least four flat sides. The sides form a passage with a first opening and a second opening. The first opening is wider and taller than the second opening. At least one of the four flat sides includes one or more slots for attaching a bag such as a leaf bag. The funnel can be pre-formed or cast. However, the funnel preferably is made from a flat piece of material that includes at least two end sections, at least three middle sections, and creases between the end sections and the middle sections. When the piece of material is folded at the creases such that the end sections at least partially overlap, the piece of material forms the funnel.
