A valance is a short drapery panel installed to sit at the very top of the window with either a drapery rod or sometimes stapled to a back panel board. Valance guarantees a soft appearance that can look casual or formal depending on the style and the mood that the room requires.


A cornice is similar to a valance in that they top off your window treatment to either hide hardware or add a pop of accent color to improve the room design, making cornices a great addition to your room design. What makes a cornice different from a valance is the construction. Cornices are considered a hardtop treatment because the fabric is often upholstered on a board with no fabric hanging loose at the bottom. This gives a clean finish and why it's preferred in modern interiors. Cornices can be made with different materials or shapes and various shapes and sizes, depending on the look you're going for.


3 Blind Mice Window Covering offers window valances and cornice made of two different material types to choose from wood or fabric available in countless colors and styles. Valances can be mounted on rods or poles, boards and used in combination with or without drapery panels. We offer various options that can involve customized options, a fusion of existing treatments, or a creation of your own. The shape and style of the window, the other treatments you are considering, and a budget will help us determine the project's scope.


Fabric valances add a soft finish and are available in the widest variety of colors, patterns, and textures and can easily be designed to fit your existing decor.

Swags, Cascade & jabot

Also referred to as a swag, the cascade in a curtain valance softens the look of your windows and is usually accompanied by a jabot, a fall on either side. The cascade is designed in a half-moon shape, giving it a soft, draped look with deep folds.


There are also wood valances known as cornice, designed to add an extra special touch to treatments or add luxury to an already elegant drapery look.

Palladian Shelf

Does your window have a unique shape like an arch? A specially designed, palladian wood shelf allows blinds and shades to be easily mounted underneath to feature the beautiful curve of your window.


Cornices boxes are designed and carved from wood and stained to look attractive without paint or fabric coverings, which provides a more formal look to a bedroom or kitchen.


A padded cornice gives a softer, more textural feel to the room by upholstering fabric on the surface of the cornice. Because of this, the padded cornice box offers the same soft treatment look but with more form.


The safe thing to do is to select a color from the overall design in the room and reprise it with the color of your valance. But don't be shy to choose a color that will pop from the wall color. If contrast is not your thing and you want to match the fabric to the wall, you should still consider selecting one or two shades lighter or darker to create dimension and depth. At 3 Blind Mice, we have over 400 different options to choose from for your cornice box fabrics!


Blackout shades will cut out the majority of light, giving you the darkest possible room; however, the "halo" light that seeps through the top and the side can be reduced by multi-layer treatments that combine side panels and a cornice box or valance.


The center of family gatherings and all fun parties always seem to end up; the kitchen is one of the most highly trafficked rooms in any home. By adding a stylish window treatment, your kitchen becomes even more inviting. Valances are a popular kitchen window treatment option where floor-length draperies become impractical, usually measuring about 18 to 24 inches in height, only covering the top of the window, depending on the size of your window. We offer valances for your kitchen made with material that is very durable and easy to clean with a damp cloth so that it can withstand all kinds of kitchen conditions, so you don't have to worry about stains and warping. The general rule of thumb for the valance length should be 1/4 the window height plus one inch.

Kitchens are often the heart of the home. And with 3 Blind Mice, you are in complete control of the design and look, all the way down to the minor trim, so you can be assured a stylish window fashion that withstands heat, moisture, and dirt.

All drapes are prone to dust, but valances, in particular, are dust magnets. So if you've been sneezing a lot or if you've noticed a layer of gray buildup, it's time to treat your valances to some maintenance.

  • Dusting - Did you know that we can clean your shades and valances without even removing them?
  • Vacuuming - A handheld vacuuming tool will do wonders in sprucing up your valances.
  • Spot Cleaning - Use a soft cloth or sponge moistened with lukewarm water and mild detergent. To avoid creasing or damaging the fabric, blot gently. This method should be avoided on delicate woven fabrics.

A variety of materials can be used to create top treatments depending on what type of treatment you are interested in. Cornice boxes and valances and more structured and popular options include wood, metal, fabric, and even natural materials such as bamboo or woven grasses. Whereas top treatments like swags and scarves are made of fabric ranging from cotton and linen to silk, or polyester and can be designed in a range of styles, from pleated to gathered to tailored. When selecting a material for a top treatment buyers should consider the style and function of the room, as well as their own personal preferences and budget. It is also important to keep in mind the maintenance requirements of the material, as some may require more care than others.

Measuring for a top treatment is crucial to ensure the right fit and style. Buyers should measure the width and height of the window, add extra length for the desired style, and account for any hardware that may be used for installation. At 3 Blind Mice, we will take accurate and precise measurements noting all the architectural features that must be accommodated—windows, doors, moldings, built-in furniture, and more.
