Regular vs cascading Roman Blind folds

At my one day Roman Blind making workshop, you will learn how to calculate Roman Blind folds. This will include finding out about both regular and cascading folds. When making a Roman Blind, it is important to understand the workings of the blind. We look at examples of blinds which I have made to understand the concepts. This helps to visualise what you are trying to achieve from your project.

What is the difference?

Regular folds

Regular Roman Blind folds are much simpler to calculate and measure out. Each fold of the blind is the same length. When raising the blind, the folds stack up level with each other. This type of blind is ideal if you want to let as much light as possible into the room. If the window is small, regular folds will keep the blind in proportion with the window. If the blind is in a sunny window, over time the fabric at the base of the folds can fade.

Cascading folds

The cascade is the fabric which shows at the base of each fold. In the U.S. a cascading Roman Blind is also known as a Waterfall Blind. It creates a look where the folds are cascading like a waterfall. The Cascades can vary from half a centimetre to several centimetres.
These blinds tend to be more popular. The cascading effect gives a wow factor and can also enhance the choice of fabric. They also cover more of the window. This is beneficial for ensuring the proportion of the blind in relation to the window is correct. The blind should cover between 1/5 and 1/6 of the length from the top to the bottom of the blind. This is when the blind is in it’s raised position. as mentioned before, the sun can fade fabric. With the cascading blind, it means that folds are not exposed.
