How to make lambrequin curtains

Updated November 22, 2016

Rich in style and design, a lambrequin curtain decorates a window with an elegant arch that dresses up the top of the window using a padded, fabric covered board. By making your own lambrequin curtains you can save on the costs of professional construction and installation while getting to choose the arch and fabric you like best. As you make lambrequin curtains, select a fabric that coordinates with the room you are working in to get a uniform effect.

Measure your window's width just inside the frame. Measure the length inside the frame and divide by three. Mark and cut a piece of plywood to this width and divided length.

Make a few sample sketches of symmetrical scalloped archway designs on a sheet of paper. A lambrequin has three straight sides, and one of the long sides is cut, so the more intricate the pattern the more difficult cutting will be, so choose a design from your samples that suites your skill level with the jigsaw.

Draw the pattern you have decided on onto the plywood so it is symmetrical. Cut along the drawn line using the jigsaw to create the plywood base for your lambrequin.

Spread a piece of fabric out onto the floor with the pattern facing down. The fabric must be at least the length and width of the plywood from Step 1 plus 6 inches on both measurements. Smooth an equal sized piece of cotton batting over the fabric.

Lay the plywood over the fabric and batting layer and centre it so the sides of the plywood are 3 inches away from the side edges of the fabric and the top is 3 inches away from the top of the fabric. Trim the bottom edge of fabric and batting 3 inches out from the cut line on the plywood.

Wrap the fabric and batting layer around the edges to the back of the plywood starting along the top and sides. Staple the fabric to the plywood every 3 inches to secure. Wrap the fabric around the curvature of your scalloped arch pattern, taking your time to create smooth angles, and staple as you go.

Hold the L-shaped brackets a foot apart along the top edge of the plywood. Adjust the brackets so the corner of the L shape runs even with the upper edge of the lambrequin. Screw the brackets to the plywood.

Lift the lambrequin and hold it inside the window casing with the arch pointed downward and the brackets facing into the window. Screw the brackets in place along the window frame to secure the lambrequin curtain.


Hang a matching curtain or shade inside the window's casing just behind the lambrequin to provide the ability to screen the window and enhance the look. Add beaded trim, fringe, tassels or piping to the bottom edge of the lambrequin for extra style. Make the lambrequin longer than a third of the window for a more dramatic effect.
