Carve a scalloped pattern into an everyday shade and you'll have a pretty way to let the sun shine in: Daylight will peep through the slits, adding a bright touch to your window decor while creating a shadow effect. 

Download and print the template. Print as many as needed to fit the width of your shade, following directions on template. 

Using painters' or masking tape and a ruler, affix templates to shade, positioning them about 1 1/2 inches from bottom edge. 

Place shade on a cutting mat, and use a craft knife to cut through shade along the lines of the template. 

Make sure to leave space between cuts as marked to keep bottom of shade attached. Hang shade according to manufacturer's instructions.
