Yes. As a package or,

If you already have rods, you can get new double rod brackets.

Maybe find them locally or on the web from the usual places.

I don't have the rods yet. I am looking online and trying to discern how much space they are allowing between the rods. If you have a specific one you can refer me too I'd appreciate it!

I do not have any double rods but am shopping them.

Most *should* have enough projection for a layer of sheers and a layer of grommet curtains since grommet curtains are so popular.

If the distance is not stated, then you have to look for other info and compute it yourself for a rough estimate of the distance between the rods. Like this info on a set that I'm looking at: Projection from wall to back rod is 3 inch, wall to front rod is 6.25 inch.

If not in the description, then look at the Q&A's on the product, in the reviews & at customer photos of the actual installed product.

This looks like it would work from Wayfair I think it is called Greyleigh
