I recently made a quilt with applique. The applique was adhered with fusible stuff...I don't know what it is called, but I iron the pattern onto the back of the fabric, then cut along the lines, then take a pin to take off the backing leaving the pattern to be ironed on the quilt, then I used a buttonhole stitch to finish it off. (I don't know if I said that right). But after the quilt was finished, I noticed that the quilt was stiff where the applique is. Any reason why it is stiff and will it soften up after washing it??
