I made valances for my living room. Here’s how I did it!
Step 1. Figure out how wide you want the valance to be. I decided to make mine 50 inches wide, which is the same width as my window plus window frame. Once you figure out how wide you want your valance to be, add 4 inches (2 inches on each side) for seams. So my starting fabric was 54 inches wide.
Step 2. Figure out how long you want the valance to be. I think 16 inches is pretty standard. Because the fabric wraps all the way around the back of the valance, you’ll want to cut your fabric twice the length of the final product. So, I cut my fabric 32 inches (actually, I cut it 33 inches to give myself a cushion for error) by 54 inches wide.
Step 3. Fold and iron to create clean hems. fold down 3 inches on top, 2 inches on each side, and 1 inch on the bottom.
Step 4. Bring up the bottom of the fabric so that the top and bottom hem folds overlap by 1/4 of an inch or so.
Step 6 (optional). When finished sewing, I went back and ironed the bottom of my valance where fabric folds and wraps to the back. I didn’t want to do this prior to sewing because I feared it would cause my pins to get moved around too much.
Step 7. Hang and enjoy!
