How can I stop my sharp metal pin hooks from snagging the delicate fabric of my curtains?

Always insert the hook into the **buckram** (the stiff, white reinforcement tape at the top of the curtain) rather than the face fabric itself. If the fabric is exceptionally delicate, use "plastic heavy-duty hooks" which provide similar structure without the sharp metal points. As suggested by seasoned sewers on Reddit, ensuring the hook tip is always covered by the header tape is the best way to prevent unsightly snags and tears in expensive custom drapes.
