The Gold Number 1 Iron-On Fabric Patch is a gold-finished, iron-on patch in the shape of a number that attaches to fabric using heat with an iron or heat press, eliminating the need for sewing. It's commonly used to personalize sportswear, backpacks, or t-shirts with a number of your choice, creating a decorative effect similar to a personalized sports jersey. The number 1 is a popular choice for marking first place or simply as a decorative motif on sportswear.
