How to Make a Board Mounted Valance

A couple weeks ago I showed you how we created the DIY window cornices in our kitchen. Well I wanted to do a little something different for our hearth room so instead we decided to create professional-looking Board Mounted Valances… and here’s how.


I purchased some 51 inch wide valances online that was a great fabric and pattern, plus had a fun detailed trim and scalloped edge. Since I wanted the valances to look professionally installed I opted for the Board Mounted Valance installation with some simple 2×4 boards I had in my basement from a previous project.

So if you add the two side widths, that was 7 inches total off my valance fabric length, leaving me with 44 inches for the broad side of the board for the remainder of the fabric valance that is 51 inches wide.

As noted the side of each board is 3.5 inches so I measured and marked that on the back of each valance on the left and right sides. Once everything was marked I ironed a sharp crease in all 5 valances for the hearth room.

Line up the marked edge with the top of the window, then draw a line just above the paint stick. Mark TWO SPOTS above every window for the L brackets.

    Very pretty! I like the detail on the bottom!! Thinking of doing this to my dining room but actually making the valance myself. I have a hard time finding curtains I like not to mention the prices are outrageous! I just bought curtains for my living room and couldn’t find sheers I liked so I bought a stamp and some paint that matched my new curtains. Stamped away yesterday! Love the way they came out!

      The Velcro brand actually makes some specifically to be used with fabric. Some are heat activated and some are just industrial strength bonding (which is what I used). Hope that helps! I purchased it from Lowe’s ;)
