Women-owned and printing garments since 1994, T-Shirt Mart in Point Loma runs silkscreen, embroidery, direct-to-garment, direct-to-film, and vinyl heat-transfer lines from its Sports Arena Boulevard production floor near Pechanga Arena. Walk-in same-day turnaround starts with an on-site design consultation at one of four-plus graphics workstations, a print-to-pickup speed that complements the paper-and-large-format output at Thirty One Ten Printing. Four San Diego County locations — Sports Arena, National City, El Cajon, and Kearny Mesa — share production capacity, so a rush order can route to whichever shop has available press time. Team jerseys, school uniforms, corporate polos, and event merchandise each follow a different decoration method chosen during the consultation: silkscreen for high-volume single-color runs, DTF for photographic full-color detail, embroidery for textured logos on structured fabrics. Custom rubber stamps and embossed branding materials from California Stamp Company extend the branded-merchandise pipeline beyond garments into stationery and packaging. Multi-method bulk orders — screen-printed tees, embroidered hats, and vinyl-numbered jerseys produced as a single coordinated package — are the shop's most complex project type.
