Single pleat curtains are a type of curtain that is made by creating a single fold at the top of the curtain1. This creates a modern look and allows the curtains to stack efficiently like a triple or double pleat. Single pleat curtains are the most common type of pleat and are used when you want a casual, relaxed look for your curtains. To achieve this look, simply fold your curtain in half and tuck the two sides into each other, creating a single bubble or bump on either side of the curtain.
