When you sew an American flag onto a patch, it creates a piece that stylishly and proudly represents America. The flag's stars and stripes are sewn onto twill backing with durable polyester threads. Just like other cultural embroidered pieces, these patches are subject to U.S. flag code. Among other items, soldier’s uniforms, patriotic souvenirs, and crafts celebrating American heritage also incorporate these patches, which come in 3D puff stitching or tactical reflective threads. For overseas/cross-border occasions, commercial markets may change the designs while respecting local laws pertaining to the country’s symbols.
