Abstract: A trash and leaf bag foldable insert can be selectively placed into either of at least two differently sized bags, in a folded condition and then expanded to maintain the bag in an open configuration so that the bag can be filled with debris or other material. The insert includes a plurality of upwardly oriented spikes along the top edge for holding larger bags, and another set of upwardly oriented spikes inside openings located below the top edge for holding smaller bags.
