Using Curtain Linings

Lining your curtains is usually a good idea, and offers the following advantages:
- blocks out more light
- gives you more privacy
- curtains hang better
- gives better insulation against noise
- keeps in more heat
- gives a uniform appearance to windows from outside (if the linings match)
- makes curtains last longer - the lining protects them from fading and dirt
In addition to standard lining fabrics, there are flame-retardant linings, and fabrics that totally block out light.
A thermal interlining (an additional layer of fabric between the curtain and lining) improves both heat and sound insulation, and makes the fabric look much fuller.
