3D Puff Digitizing is a specialized embroidery digitizing technique used to create raised, three-dimensional effects on designs, commonly seen on caps, hats, jackets, and sportswear. This process involves converting artwork into a stitch file that is optimized to work with foam underlay, allowing the embroidery to “pop” above the fabric surface for a bold and textured appearance. https://digitizingpatches.com/3d-puff-embroidery-digitizing/
