Make a mark four inches up from the bottom on both sides of the shade.
Start at one side of the shade at the four-inch mark, and run a piece of tape across to the opposite four-inch mark. Try to keep the tape as straight as possible, if necessary, use a yard stick as a guide.
Measure four inches up from the tape and repeat the previous steps until the entire shade is covered with horizontal tape lines, all four inches apart.
Mark the centerpoint on the bottom tape line. Measure two inches from one side of centerpoint and make a mark. Make another mark two inches from the other side of the centerpoint, so you have two marks four inches apart to start your vertical lines. Repeat the process so you have marks on the opposite end of the shade and in the center.
Run a line of tape, from bottom to top at the four-inch marks. Repeat the steps to create 4” x 4” squares on the entire shade.
These squares don’t have to be perfect, they are simply a guide for stamping. So don’t worry if the lines aren’t perfectly straight.
Thoroughly blot the first stamp on the ink pad, making sure to cover the entire stamp. Stamp alternating squares on the shade with the first stamp. Make sure to blot the stamp pad between each application.
Use a second stamp in the alternating open squares. Alternating the two different stamps creates repetition and pattern, two very important design elements.
Be sure to use permanent stamp ink.
Secure the hardware to the window frame using the screws provided with the hardware. Repeat steps to secure the hardware on the opposite side of the window frame.
Hang the shade by sliding the appropriate ends into the secured hardware brackets.
Pull the shade down to desired height.
