1. Use clips, grommets or rings. Most curtains comes ready-made with a pocket to push the rod through--don't use it. Spend a few extra dollars for the proper hanging hardware. This looks nicer and it is more functional. It is much easier to pull your curtain open and closed when it can easily slide. Plus the top of a bunched up, scrunched up curtain is the perfect place for a bunch of dust to collect.
2. Pinch a Pleat. Take a couple extra minutes when hanging your curtains to pinch a pleat. This gives your curtain some symmetrical movement when they are both pulled closed and opened.
Lay your curtain out flat on the bed, the dining room table, or the floor. Pinch a pleat in the center of the curtain and then on each end.
Divide the space between the center and the ends by how many rings you are using and pinch a pleat and clip on the ring.
Your curtain will hang with a pretty, symmetrical, fool-proof wave.
3. Flank the sides of the window. You hear it all the time on our favorite HGTV shows, but I just felt it bears repeating. This tip can make an offset window look centered, add luxury, make a window feel bigger and a room appear larger.
4. Hang floor to ceiling. Curtains hanging from floor to ceiling add elegance, sophistication and make the room feel bigger. Can't find the length you need? Check out my article on stretching your curtains and your budget.
