How to Make a Custom Valance


Custom fabric accents add visual interest and complete your window treatment, adding a final flourish for added visual appeal in any room. They can be casual or formal, depending on their material selection. Pick out the custom Roman shades.

Start by cutting a 2-by-4 or 1×6 piece of wood into pieces that measure two feet by four feet, adding quilt batting, then covering them with the fabric of your choice.


Valances come in various fabric patterns, colors, and prints to fit into any decor, providing the perfect accent piece to curtains, blinds, or shades. Custom-crafted valances can also add the finishing touch to curtains, blinds, or shades – they make an eye-catching visual addition! You can create one using any strong drapery fabric that can tolerate iron heat and fabric glue as an easy no-sew option; allow plenty of time to set before stapling or stitching!

Before beginning, determine how wide and tall of a valance you want. Your preference could range from matching the window’s width to widening it for dramatic effects. Height options are up to you, but remember that the higher you go, the bolder its impact will be.

After selecting your fabric, cut it to fit inside the valance box. If using patterned material, match its direction on both sides of your valance has an angled end.

Flat rod pocket-mounted valances can usually be completed within 1.5 hours, while elaborate board-mounted ones may take up to 10 or more. Curved edge box valances require even longer.


Valances can provide an attractive way to conceal window blinds or roller shades while adding an eye-catching decorative element that fits many decor styles. Furthermore, this type of window treatment may also block light or prevent drafts from coming through open windows; no matter your window style, we guarantee we have something suitable!

When you’re ready to create your custom valance, the first item on your shopping list should be the fabric for the top and sides of the valance. The width will depend on your window size; adding bands or accent trim may give it some added flair. In addition, consider whether or not using lining fabric may help protect it against sunlight exposure fading it a bit faster.

Before attaching fabric to wood, cutting a piece of lumber to fit is necessary. Doing this is accessible by measuring the width and length of your valance – then cutting or purchasing pre-cut pieces of lumber that meet those dimensions.

Box Pleats

A valance with box pleats is an elegant way to give any window an eye-catching update without sewing. Add this chic accent piece to any window treatment, or use it alone for an updated, personalized look.

To create a valance with box pleats, measure the width of your window and add 5-10” (depending on how wide you want your finished valance to be). Next, cut two pieces of 3” wide foam board for its sides. Lay down the main board, and attach fabric, ensuring its right side faces upward and it’s reverse downward (it might help to put quilt batting behind it for added support).

Press a double fold 1″ hem towards the lining side along one long edge of the main fabric and pin it in place. Next, using your sewing machine’s Blindhem Stitch #9 with Dual Feed foot and sewing the blind hem allowance of approximately 1/4″, repeat on the other long edges and trim any excess fabric using scissors.

Scalloped Edge

Scalloped edges add a stylish flourish to custom valances, adding the finishing touch. To create one, cut a strip of fabric six inches longer and four inches taller than the desired valance length, fold it in half, trim along its edges, and trim it into shape to achieve this finished look. Hemming or liquid “ravel stop” may help prevent unraveling before being wrapped around a piece of wood and secured by L brackets on its backside before finally being attached to the wall above your window.

Using a stud finder, locate and mark all studs in the wall above your window. This will be where you screw in the valance box; ensure it remains securely attached so it doesn’t move or fall!

This no-sew valance is ideal for those without sewing skills or who don’t wish to use one, making for an easy project that adds the final touches to any window.

To complete this project, you will require between 1-1/2 and 5 yards of fabric face fabric, depending on the design and size of your window, in addition to enough yardage for lining and wrapping around corners.
