My sweet mom made a cute valence curtain that I followed the basic pattern of to make this orange curtain.
Here's how to if you want to try it yourself:
Cut out 2 equal lengths of fabric. Mine each measured 22" x 50" (you could make it shorter if you like, it will just affect how 'bunchy' the valence is)
Place both pieces right side together and sew 1/2 inch seam along width edge to make one long piece of fabric. (Once put together, mine measured roughly 22" by 99")
Iron open the seam you just made. Then, stitch a 1/4 or 1/2 inch seam around entire piece of fabric.
Fold over one length of the fabric 3 1/2 inches. Stitch along the bottom of this fold. THen, Stitch another seam 2 inches closer to the folded edge. This gives you a space to put your curtain rod through.
Quick and easy way to add a splash of color.
