Padded appliqué that creates volume is an ordinary appliqué with a special material under the appliqué fabric called padding.
3D Puff (Foam), polyester batting, foam rubber and other materials can be used as such. The number of layers in the padding can vary depending on the thickness of the material and the desired effect. According to my experiments with trapunto, knitwear is the best appliqué fabric that does not crumple the padding too much.
