I've done a few appliqued quilts, and I agree with all of the previous posters. The applique I've done, I've used fusible, only to secure (temporarily) the applique in place, until I could stitch it down using the buttonhole stitch around the perimeters of the applique pieces. In that instance, the applique pieces are all small enough to be contained within one block in the quilt -- that is, each block has applique in the block. Perhaps, you could embroider (by hand) the name of the person getting each quilt? Just a thought! But using polyester batting, and then using fusible to secure the applique is risky, and it's likely you would have "melted" batting.
