Light weight, expanded polystyrene (Styrofoam) sections are simply glued together with a full sized regular low temperature glue gun (200 - 250 degrees Fahrenheit) to create your special cornice for any size window or door.
We do not recommend using a mini glue gun because you will not be able to apply enough glue quick enough to achieve a good bond.

How do I determine what height (drop) to order?
The Avalon Cornice is offered in 9", 12", and 15" drop (height) in any width that you need (up to 50’).
- The 9" Avalon Cornice looks great on small bathroom & kitchen windows. They are also popular for children’s rooms.
- The 12" Avalon Cornice looks great on standard size windows and over sliding glass doors.
- The 15" Avalon Cornice looks wonderful on very wide windows or in rooms with very tall ceilings.
- Have someone hold the paper lengthwise so that the longest side of the paper runs the length of your opening. They'll probably need to use a step stool or ladder to hold the paper in the approximate location where the finished cornice would go. From across the room, you would observe how it looks. This simulates our 9" drop cornice. If this looks too big, then you'll want the 6" cornice kit.
- Next have them rotate the paper so that it's up and down like you would normally use it. This simulates our 12" drop cornice. Does this look better than the 9" drop, or does it still look to small?
- If this way is too big, you'll want to order our 9" cornice kit. If this looks just right, you'll want to order our 12" cornice kit. If this is still looks too small, then you'll want to order our 15" cornice kit.

To determine what length Avalon Cornice to order, measure the inside of your opening and add 1-4" on each side - this is called the overlap.
If your opening has moulding around it, measure the outside of the moulding on the left side of your opening to the outside of the moulding on the right side of the opening and add 1".
But, if you have a curtain rod or vertical blind rail that your cornice will be covering, measure the length of the rail and add 1".
Pick the longest measurement from above that applies to your opening,
and this will be the inside measurement of your Avalon cornice.

The outside length of your Avalon Cornice is the inside measurement PLUS the thickness of the 2 end caps. Since each Avalon end cap is approximately 2" thick in the center, the outside length is approximately the inside measurement PLUS 4".

Can the cornice be cut specifically for my opening?
As explained above, the sections that are glued together are 16" in length. Most times the length of the opening plus the overlap on each end results in a desired length that is not a multiple of 16", requiring one of the pieces to be cut to the appropriate length. The process that you would use to cut one of the cornice pieces is to:
- Cut the pieces with something like a drywall saw, a hack saw, an electric knife, or a utility knife.
- Regardless of how careful you are, the cut will not be smooth, flat, and straight, which is needed in order to have a good bond when glued.
- After the piece is cut, stand the piece that you will be using upright on the smooth end, so that the rough end is facing upward.
- Cover the rough end with aluminum foil.
- Using your heated electric iron, pat the aluminum foil to melt the Styrofoam flat, smooth, and straight.

While this is a fairly simple process, you may not wish to try this on your own, so why not let us cut your cornice kits to length for you for only $2.00 per cornice here.
How are the cornices attached to the wall?
5" brackets and corresponding End Caps are provided with our kits. This means that there is 5" of clearance between the wall and the back of the cornice.
You may wish to substitute 3" brackets for the standard 5" brackets to move your cornice closer to the wall, providing a 3" clearance. If you would like to replace your Standard 5" Brackets and End Caps with 3" Brackets and End Caps, the charge is an additional $3.00 for each cornice.
While our 3" or 5" brackets will be perfect most of the time,
occasionally you may need custom made brackets for your application.
We have made custom brackets as short as ⅛" and as long a 10".
We will make them for you using the standard 5" brackets that are
provided with your kits; this price includes removing styrofoam from the
end caps if shorter than 5",
or providing extension pieces that you will glue onto the end caps to
accommodate brackets that are longer than 5".
If you would like to substitute your Standard 5" Brackets and End Caps
for custom brackets and End Caps, the charge for each bracket is $5.00.
