I have been practicing making memory quilts and have experimented with all products and all methods and have come up with a foolproof method that makes the photos permanent. I use any kind of pretreated fabric for photo printing. After the photo is printed onto the fabric, dry it completely, then mix fabric glue with water to the consitency of heavy to medium heavy whipping cream, take a sponge brush and dab the weakened glue covering every inch. You do not want to make strokes because it will make the colors run. This will never wash out. The glue sets the ink and literally can not ever be washed. You do not want the glue to be too thick or heavy because the fabric will be too stiff. Practice on an old cloth until you find exactly the best consistency. I have used many different kinds of fabric glue and they all work.
