I cut the squares of fabric 4 1/2" by 6 1/2" so that after a 1/4" seam on all sides, the finished squares were 4" by 6". First, I traced the letters (backwards) on the back side of Heat n Bond. Then, I fused it to black fabric and cut the letters out. Next, I sewed the aforementioned squares together, and ironed the letters to the squares, with the Heat n Bond side down. Finally, I sewed the top of each square between double folded bias tape, and I had an instant, reusable Happy Birthday Banner!
