3D Puffy Foam is designed to add raised, dimensional effects to machine embroidery, helping lettering, monograms, logos, and decorative designs stand out. Each pack includes 10 pre-cut 12" x 16" sheets—5 black and 5 white—with a 3mm thickness and 45 Shore C hardness. The larger sheet size provides more working area for different embroidery designs and can be trimmed to fit your project. Simply place the foam over the fabric, embroider directly on top, and remove the excess foam around the finished stitches. Durable and washable, it is ideal for hats, hoodies, sweatshirts, bags, apparel, logos, and DIY crafts. OEKO-TEX® certified for added confidence in material safety. | Poolin | | 3D Puffy Foam for Machine Embroidery 12" x 16", 5 Black + 5 White, 3mm Thick Foam Sheets for Hats, Hoodies & DIY Crafts | Best Buy
