The Memory Box Stitchable Mitten Dies from the Winter Days Collection are made from durable steel and compatible with most die-cutting machines. These versatile dies can be used on materials like cardstock, felt, fabric, or shrink plastic, allowing you to cut, stencil, emboss, and create with ease. This wafer-thin die set includes five dies that cut out 14 designs, detabbed and mounted on a magnetic sheet. The mitten, which measures approximately 3.2 x 4.1 inches, is designed to be sewn together, allowing you to stitch the pieces for a charming handcrafted look. The set also includes decorative elements like flowers (0.4 to 0.8 inches), a 0.5 x 0.5 inch button, and leaves (0.5 x 1.1 inches and 0.4 x 0.8 inches) to add extra detail and embellishments to your stitched mitten.
