The Studio Light Hearts Layered Embroidery Mask makes creating string art simple and enjoyable. Begin by using the plain mask to ink up your projects, then place the mask with pre-made holes overtop. Use the Puncture Tool sl-to-ppt01 (sold separately) to punch holes around the heart designs. Afterward, take a needle and thread to add beautiful sewing details. The stencil measures approximately 5.8 x 8.3 inches and features a wide variety of hearts in all sizes, making it perfect for adding charming embroidery details to your crafting projects.
