if they are the same type of fusable transfers like on t=shirts you can add them to your quilt- you have to always make sure if it is laundered it is done so in cold water-gently- and air dryed- no heat- a wall hanging would not be an issue- but it is possible to use them on a quilt too....just apply them correctly-according to their instructions & treat them with care- shirts it is generally recommended to launder them inside out- that really isn't so easy with a quilt- but it could be folded with the decals folded toward the center then washed gently- or spot cleaned when needed.
