I am not an expert by any means but what I did was cut my hearts, iron freezer paper to the wrong side, then press 1/4 under. I removed the paper, basted hearts where I wanted them & then blanket stitched it in place.It was a lot of steps but it worked great. The stabizer would be encased within the 1/4 allowance. I guess I am anal about having unfinished edges. I love the blanket stitch look though.
