Quick and Easy. To sew or not to sew? How about no sew?
Step 1. Iron your pillowcase.
Step 2. Turn it over and fold over top (I did 5.5"). Iron the crease.
Step 3.
Hang your valance over an ugly cheap metal curtain rod.
Step 4. Step back and marvel at yourself for making a valance in less than 10 minutes. You might even want to give yourself a hug, or high five the air...maybe even a fist bump. Either way, when it's all said and done, let out a big "Boo-ya! Look what I just made, I'm awesome!"
