Cellular shades are attractive, work easily and are extremely energy efficient. Most stores offer shades custom made to your dimensions; they also offer free cutting service to customers who buy generic in-store shades. To have the shades cut at the store, you need to know the exact measurement of the window where the shade will be installed. If the shades are cut incorrectly and you want to re-cut them, if you want to cut the shades yourself from the beginning, this is not a complicated project to do.
Things You'll Need
- Cellular shades
- Table saw or power mitre saw with fine-tooth finish blade
- Pen or pencil
- Tape measure
- 1 1/2-inch or 2-inch masking tape
Determine whether the shades will be installed inside or outside the window frame. Measure the desired length of the shade. If installing outside the window frame, the length should be at least two inches wider than the window frame. This allows one inch on each side of the frame for installation clearance. If installing inside the frame, measure the exact width of the inside of the window frame. Subtract one inch, allowing for a 1/2-inch clearance on each side of the shade.
Measure the actual length of the shade. Do not assume the sizes on the package are accurate. Subtract the desired length from the actual length to determine how much you need to cut off. Then divide the amount you need to cut off in half to determine the amount you need to cut off on each side.
Note: You must cut an equal amount off each side, or the shade will not work properly.
Measure from the end the amount needed to cut off. Retract the shade and wrap both ends tightly with the masking tape, covering the point where the shade will be cut. Make sure the ends are square. This keeps the shade from shifting or cutting crooked, and will keep the shade from snagging or fraying.
Carefully re-measure the amount needed to cut off on each side, and mark on the tape.
Using the mitre saw or table saw with mitre guide, carefully cut the shade at a 90-degree angle.
Remove the tape and install the shade.
