Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to build a folding screen [title] Gather 3 plantation-style shutters. [step] If buying new shutters, purchase 3 of the same size. If you're buying salvaged shutters, trim them so that they are uniform in size.

Ending1: [title] Lay the 3 shutters across 2 sawhorses with the top edges aligned. [step] Clamp them together in several places so that they will not move while you do any necessary repairs. Ending2: Bigger shutters will dramatically hinder the shape of your planter to avoid clutter. You will want your shutters to be triangular in appearance, so choose shutters that are equal with the width of your planter to ensure a clean, geometric look. Ending3: The shutters do not necessarily need to be open wide or narrower. Extending stays allow the material to hang downward instead of being folded vertically. Ending4: You can cut the shutters themselves, or you can glue a planed panel to them to serve as a dome. [substeps] You can also choose to buy new planed panels from a hardware store, or borrow pre-made shutters from a friend.
