What type of room is it? The window treatment needs to commensurate with the function of the room and therefore is a deciding factor.
The preferred style and theme for the home will also dictate the design and overall feel of the type of window treatment, materials and colors used.
Generally, short curtains use less material and are cheaper to make than long ones. Standard length of short curtains are five feet or 60”. For extra elegance or if nothing is obstructing the length, most look better at 66 - 70”.
Get coordinated by using leftovers (or just purchase one metre) of your curtain materials to make cushion covers, table runners or napkins.
Matching colors and prints to existing theme is easier if you work with the fixed items first, such as sofa, cupboards, wallpapers and paint.
For rooms with smaller windows, a single track with double layer stitched together may achieve a look of a double layer curtain.
You can save more by using sheer materials as day and night curtains (If privacy is not an issue). Different colors and textures may give a lighter feel.
Not sure what color to give your child? Girl’s rooms are normally pink or purple with white furniture. Boy’s rooms are normally blue themed. You can throw in fun designs or prints.
