1. Choose your curtain type.
2. Choose width and length.
3. Choose your curtain rod.
4. Choose where to install your curtain rods.
5. Hang your curtains.
6. Hem your curtains.
Valences don’t need to be hemmed, but for full-length curtains, hem the bottom 4-6 inches so that the hem is below the bottom of the sill. Letting your curtains hang closer to the floor can give you an elegant look, but make sure the curtains aren’t dragging when you open and close them.
