Choose curtain headings for the rail you have
Eyelets, pockets and tape headings ask for different hardware. Check the connection before choosing the fabric.
Match the top edge to the support
An eyelet curtain slides directly onto a compatible pole. A rod-pocket curtain threads the pole through a fabric channel. A taped heading may use hooks and rings or a suitable track arrangement. Those differences determine both how the panel hangs and how easily it moves.
Look at the hardware already fitted. Measure the pole diameter and check that eyelets or pockets have enough clearance. For a track, identify the gliders and hooks rather than assuming any hook will fit. If replacing several parts, ask the supplier to confirm the complete combination. A photograph of the existing track can be more useful than guessing its name.
Check whether the heading parts are included with the curtain. Hooks, rings or gliders may be sold separately. Count what is needed for the intended fullness and spacing rather than buying a packet at random.
How often will you open it?
A decorative side panel that rarely moves can tolerate a heading that takes more effort to slide. A bedroom curtain opened every morning should move without pulling hard on the cloth. If a rod pocket grips the pole tightly, forcing it each day can become irritating even though the curtain looks tidy when arranged.
Consider the space occupied by the gathered fabric. Some headings form a substantial stack beside the window. In a narrow recess, that stack may cover more glass than expected or obstruct a handle. Open and close a sample if possible, and look at the panel from the side as well as the front.
The heading also changes the measurement point for the drop. Do not order a new style using the old curtain's overall length without checking where each style sits relative to the pole or track. A few centimetres at the top can become an unwanted gap or dragging hem at the bottom.
Make removal part of the choice
Eventually the curtain will need cleaning. Think about how it comes down, where removable hooks will be kept and whether you can safely reach the support. Follow the fabric and hardware instructions when laundering; some parts must come off first.
When several windows share the same style, label removable pieces by room during cleaning. Similar-looking hooks can have different settings. A heading that you can remove, clean and rehang correctly is a better match for a busy room than a more elaborate arrangement you are reluctant to touch.
