Net curtains are inexpensive, lightweight curtains that allow light to enter a room but provide a measure of privacy. Often these curtains are made out of voile or thin lace fabrics. The top of the curtain uses a type of tight header similar to pencil pleating that gathers the curtain fabric tightly. This tight gather adds a sense of opulence to the drapery. Nets are often positioned behind heavier curtains, and it is common for the net to slide along a rod or pole to open and close.
Place a short ladder in front of the window. Measure the inside width of the window and multiply by 2. Measure the length of the window from the inside bottom of the window casing to either the windowsill or the floor. Buy net curtains to fit your measurements.
Thread clip-type curtain rings onto a tension spring rod. Install a tension spring rod at the top back of your window casing.
Place your curtain face down on a table. Position header tape across the top of the curtain and pin the tape about 1.2 cm (1/2 inch) from the edge. Fold each side under 1.2 cm (1/2 inch) for neatness. Do not pin the cords.
Knot the cords on one end of the header. Sew the header tape to the back of the curtain. Sew between each cord. Sew in the same direction each time to keep the header from puckering. Pull on the loose cords until you achieve the gather you want. Knot the cords close to the header. Wrap the loose cords into a small ball and place them into a cord tidy bag. Safety pin the bag out of the way.
Clip the net to the curtain rings starting at each end and then evenly spaced across the curtain.
For two curtains on one window, buy two nets the width of the window. Gather both and hang both on the same rod.
