Arched windows add architectural interest to a room with the wood moldings providing texture. You may think about adding draperies at some point to control the light coming in the room.
You have the option of using a flexible rod if you don't want to hide the molding or a traditional rod to cover molding. Eliminate rods altogether by using curtain knobs Install arched window curtains by following these steps
Prepare to Install the Curtains
To complete the installation, you need:
- work gloves
- step-ladder (optional)
- fabric pencil
- wall anchors for drywall
- stud finder (optional)
- curtain rods or knobs
- metal toggles (optional)
- curtain panels
If you choose flexible rods, don't hang heavy curtains on them. You may prefer to pinpoint wall studs with a stud finder in place of using anchors. A fabric pencil mark can be erased or, it will fade with time. If the material is heavy, install metal toggles.
Measure for Curtain Rods
Set a step-ladder to reach the top of the window, if necessary. Measure the length between the vertical side and where it joins the arch. To get rod length, tape a string or rope running from the beginning of the arch to the end, remove the tape. Larger windows may require two rods and two panels.
Measure the points, adding six to eight more inches or enough to accommodate rod return, or rod distance from the wall. The extra width ensures the curtains hang properly with the right pleats.
Multiply the length by two for heavy fabric, two and one-half for medium fabric, and three for sheer curtains. For wide windows, add four inches.
Drill the Holes
Hold a level on the arch, and mark each end an eighth-inch over the end of the straight sides. Set a bracket on these marks, and mark the position for pilot holes.
Drill the pilot holes, and add anchors making them even with the opening, if needed. Thread the curtain through the loops on the curtain panel. Attach the bottom rod in the same manner.
If the curtain has a rosette strap, connect the two ends. Gather a fist full of material similar to making a pigtail, pull it through the strap, and smooth it.
Install the Knobs
To measure for knobs, draw a line across the perimeter of the arch, Measure the line, and divide the figure by the number of pleats, then add one.
Make a mark every ten inches to indicate knob placement. Figure the center of the marked line, then attach two knobs at each mark according to directions.
