So I'm wondering what I can put at the bottom of a curtain to make it not only 3 inches longer, but blackout at the bottom as well. I could add 3 inches of lace. But blackout backing is white. So it would be blatantly white at the bottom of the curtains, even with black lace sewn to the bottom of the black curtains. Plus I can't sew.
What could I add to the bottom of blackout curtains to make them 3 inches or so longer?
