Trim & Install

If page 1 told you have you an imperfect arch, follow these

steps:

To determine where to cut, take your width (A) and height

(B) and compare half of A to B. If half of A is larger than B,

trim at the original width measurement. If B is larger than

half of A, trim at 2x the width measurement.

For example, if your window is 30” wide and 14” tall, trim

the shade at the 30” mark on the cutting guide. If your

window is 30” wide and 16” tall, trim the shade at the 32”

mark on the cutting guide.

We trim at the larger of the two measurements to allow for

room to work with when trimming off excess whether your

window is taller or wider than a perfect arch.

With the initial cut made, fan the shade open in the window.

DO NOT adhere the shade. With a pencil or pen, trace the

curvature of the arch on the excess material.

This traced line will allow you to cut off the excess at the

top or sides of your shade to make for a perfect t in your

imperfect arch window.

Example: For this window, half the base is slightly larger

than the height. We would trace the curvature of the top of

the window to trim the slight excess at the top of the shade.

Remove the traced shade from the window. Using a pair of

sharp scissors, cut along the line you made to remove the

excess material.

Once the shade has been trimmed, place the shade in the

window to ensure it is properly trimmed. Then, install the

shade as shown on page 1.

Please note: Our trimming scale is designed for perfect arches only. This method is for modifying Original Arch

shades for slightly imperfect arches. If you have a signicantly wide, narrow, or eyebrow arch this product and

guide may not work for you. If you do have a specialty arch, we would recommend a custom window treatment.
