Yup, you read that correctly. I did indeed make a window valance using foam core and duct tape. Why did I do that? Because I was too lazy to go to Home Depot and have wood cut. That and I have some experience with building things from foam core. One of my design classes involved creating a masterpiece model using only foam core and pins. It was one of my favourite projects and I'm always looking for ways to build new and exciting things with this stuff.
Damn you blinding light for messing up my photo:(
1. Measure your window and make sure if there is a curtain rod hanging that you measure to go around the end of the rod. I used 3 pieces of foam core and using a box cutter I cut it to the height I wanted.
2. Tape all your pieces together.
3. Create a paper template based on the shape you want your valance to end up being. I just used old Christmas wrapping paper and started sketching until I found the curves that I like.
* I forgot to photograph this step but in order to create the sides of the valance measure 6 or 8 inches on each side. Score the foam core cutting the top layer but not all the way through. Bend it and it will create the fold you need for the sides.
5. Repeat with fabric. I also added some gros grain ribbon
6. Since my valance ended up being so long (almost 6 feet) I used a piece of scrap wood to reinforce it and give it strength.
7. I used picture hangers. Just screw it straight into the foam core and then attach to the wall. Stand back and be amazed at the beauty.
And that is how you turn the lowly foam core and duct tape into beautiful objects.
