3D puff embroidery is a technique that adds a unique three-dimensional effect to embroidered designs, making them stand out with a raised appearance. It involves using foam under the stitches, creating a raised surface that gives depth and texture to the design. The foam padding creates a pronounced effect, adding a tactile element to the embroidery. This technique is commonly used to enhance logos, text, and graphics on heavy fleece hoodies, jackets, and other apparel items, making them visually striking and attention-grabbing. With 3D puff embroidery, designs become more dynamic and visually appealing, creating a bold and memorable statement.
