I just did that exact thing to the quilt for my DD. I straight quilted with my machine on some parts and then went around and stitched hearts in all the blank small odd shapped parts. Washed it twice and I just really loved the way it came out. Lots of mistakes with the machine straight stitching, but the hearts are really sweet and neat looking. I like the way the fabric puffs up after hand quilting. I know that DD will love the quilt because I never finish things, so she will be so proud of me. And will love her quilt. Don't forget to add a special label to her quilt. My label looked a little uky but she will love it...Blessings
