I have almost completed my first fusible applique wall hanging. I was busy quilting it to accent the pieces when I noticed that the edges of the appliqued pieces weren't necessarily sticking to the background fabric.

My questions are:
1 - should I sew around the edges of the appliqued pieces? If so - how
2 - can I iron it again? I still have the instructions that came with the fusible stuff.

Thanks in advance for any advice.
