Draperies and Top Treatments - Spiral Jabots

I would like to make a window treatment using a swag and a spiral jabot. I have two windows on the same wall which measure 41" W x 77" L from trim to trim. I have found directions for the swag, but nothing for a spiral jabot. Can anyone tell me how to make the jabots and also total yardage for each window? Thanks

Hi and welcome to the forum! There really are no directions for a spiral cascade. It's basically a curved pattern I made a quick sketch to show you the shape/s. It can be anywhere from the smaller to the larger size, depending on how much fullness you want. The finished length will be the left side of the pattern and you'll need one width for each cascade. You need to determine the length you want it to be and start from there for drawing the pattern. Use cheap lining or muslin for your mockup, and you really need to just play around with it and try different things until you get the look you want.

As for how much fabric you need, a basic swag generally takes 1 1/2 to 2 yards per swag. The cascade needs to be figured much the same way a drapery panel would need to be figured, and it depends on the fabric repeat and how long you want it to be.
For both the swag and the cascades, you need to make mockups first, then use that for your final pattern.
