Which type of top is considered casual or modern in drapery design?

The tab top style is recognized as a casual and modern option in drapery design. This design features fabric loops, or tabs, sewn onto the top of the curtain panel which are threaded directly onto the curtain rod. The result is a relaxed and effortless appearance that aligns well with contemporary aesthetics. This style allows the fabric to hang loosely and creates a soft, flowing drape that can enhance informal and stylish environments.

In contrast, other styles like goblet and pinch pleat tops tend to evoke a more traditional and formal look due to their structured designs that emphasize tailored lines and precise folds. The rod pocket, while simpler and less structured than the goblet or pinch pleat, still doesn't convey the same level of modern informality as the tab top, as it typically involves the curtain being gathered and pocketed onto the rod which can look more conventional. Thus, the tab top stands out as the optimal choice for a contemporary and laid-back feel in drapery design.
