Wave
Even, S-shaped folds that hang from a wave track.
Pick curtains by how the top is made: wave, eyelet, pencil pleat or pinch pleat. See each one hung, with sheer and blockout layers.
The top of a curtain is called its heading. It sets the look, and it decides what the curtain hangs from.
Eyelet
Metal rings sit in the top of the curtain and a pole passes through them.
It needs a pole, not a track.
Sources call both of these modern, and eyelet the more casual of the two.
Pencil pleat
A tape across the top is drawn into small, even gathers.
It goes on a track or a pole.
Pinch pleat
Pleats are pinched and stitched in groups of two or three, and the cloth opens out below.
The finish is tailored and formal.
"Classic" describes the look. Pencil pleat suits most rooms, and pinch pleat is also used in modern rooms.
A sheer lets soft light through. A blockout stops nearly all light.
Both can hang together, each on its own track.
Wave needs a wave track. Eyelet needs a pole. Pencil pleat and pinch pleat go on either.
What the curtain hangs from is a separate choice after the heading.
