PuffyStitch™ is a colored puffy embroidery foam used for creating raised 3-dimensional embroidery designs. Puffy Foam adds a raised dimension to machine embroidery. Embroidery puff foam sheets are non-toxic, water-resistant and machine washable, but it is flammable and cannot be dry-cleaned. It perforates cleanly when stitched through and makes the stitching stand well above the fabric. PuffyStitch™ 3D puff foam for embroidery is available in 2mm, 3mm, and 6mm thickness.
