Help. I want to make a roman blind with folds which are an equal distance from one another (cascade I think it is called). I tried Merrick and Day cascade formula but it did not work out at all. The bottom hem/ batten section was too long, the next 3 folds were the same length and the top one too short. I measured carefully. I cannot work out what I did wrong.
I have some which were made for me but cannot work out how to do it mathmatically.
Does anyone know how to work out these measurements?
