Drapes are usually made of a heavier material than curtains. Their extra weight requires hooks to hold the pleats in place and support the drapes on the hanging hardware. There are two types of slip-in drapery hooks: two-prong and four-prong. Two-prong hooks support existing pleats in the fabric. Four-prong hooks create a pleats when inserted in the fabric.
Fold the drapery on a table with the back side of its pleats facing up.
Slightly open a two-prong slip-in drapery hook with one hand and hold the drape with your other hand. Insert the hook's two flat prongs into the band below the pleat.
Slide the hook completely into the drapery band and release it so that it will squeeze together in place. The part of the hook that will attach to the hanging hardware needs to angle downward. Repeat Steps 2 and 3 to install one drapery hook below each pleat.
Lay the drapery on a large flat surface with the its back side facing up. Stick pleat tape to the bottom of the band running across the top of the drapery. Pleat tape has small channels for slipping in drapery hooks at uniform intervals.
Slightly open a four-prong drapery hook with one hand while holding the fabric with your other hand. Slide the first prong slightly in the first channel on the pleat tape. Skip three channels and slide the second prong slightly into the fourth channel. Continue this process to insert the third prong into the eighth channel and the fourth prong into the twelfth channel.
Gather the pleat with one hand at the top of the drape. Push the drapery hook entirely up into the drape band as far as it will go. Straighten the pleat on the front side of the drape so that it is uniform.
Measure 4 inches along the top of the drape from the hook you just inserted. Begin inserting the second drapery hook by inserting its first prong at this 4-inch point. Then repeat Steps 2 and 3 to complete inserting the second hook.
Repeat this process to add drapery hooks down the length of the fabric to create standard drapery pleats.
Use a short neck hook to allow excess material at the top of a drape and cover the drape-hanging hardware. Use a long neck hook to allow minimal material at the top of a drape and reveal the drape-hanging hardware.
