Curtains that just sit on the floors, this is usually a 2″ puddle. This is by far my favorite option and the one that I use most often, probably 90% of the time. I love this option because you don’t get the crooked floor look that you would get in the option above and the puddle is not long enough for it to look messy. You’re also not constantly stuck placing the puddle which makes it still very functional. It even gives your wall a little more height when the curtains sit on the floor.
Curtains that puddle 4-6″. This option would be used if you like the look, have the room and are okay with placing and adjusting the puddle when you open and close your curtains. Unfortunately, they don’t naturally take this beautiful shape when sitting on the floor – so it’s a little more work.
The very dramatic look of a heavy 12″ puddle. This is a look I would only consider for fixed panels. Panels that only serve as decorative features to frame a window, but don’t open or close to ever cover the window. It’s very annoying to always have to place such a large puddle. You also need the room to be able to accommodate the puddle. You can’t have anyone trip over them or have your furniture placed too close to them.
