Ask to see the complete design
A small cutting may show a flower but omit the space between flowers. Before ordering patterned curtains, find the full repeat and its dimensions. A short curtain could contain only part of a large motif, while a tall curtain may display the same distinctive shape several times.
Hold the fabric vertically and form a few loose folds. Some details disappear, others sit on the front of a fold, and a stripe can become part of the curtain's rhythm. The flat sample is only one view of the finished cloth.
If the pattern has a definite top and bottom, note the intended direction. Do not assume it can be rotated to save fabric or suit a wider window.
Compare the pair, not one panel
Two curtains meet at the centre and sit together even when open. Ask the maker how the pattern will be positioned across the pair and whether any particular motif placement is included in the service. Expectations about matching should be settled before cutting, not after delivery.
For ready-made curtains, inspect the product information and images without assuming they promise bespoke placement. A repeat may look slightly different on each panel depending on the construction. Decide whether that is acceptable for the design you have chosen.
Pattern matching can increase fabric requirements. Use the maker's calculation with the exact repeat, drop and heading. Multiplying window width by height does not account for the way patterned drops are cut and aligned.
Give the print enough space in the room
Compare the curtain with the rug, sofa and any patterned wallpaper. Similar-sized, high-contrast motifs can compete even when their colours agree. A change in scale or a plain area between them may make the combination easier to read.
Look at the open stack beside the wall. A large botanical pattern can become an abstract mix of colours when gathered, which may be attractive but different from the clear illustration on the sample. Make sure you enjoy both appearances.
Keep the fabric code, colourway and order details. If buying material yourself, ask the supplier about batch consistency and the quantity needed before purchasing separate lengths. The goal is a pair that works as one window covering, not simply enough pieces of a favourite print to reach the floor.
