JLN COSTUME MOUNTING LLC

JLN Costume Mounting LLC specializes in the design and fabrication of custom textile and mannequin mounts for museum and cultural heritage exhibitions, leveraging precision craftsmanship and conservation-grade materials to support the safe display of delicate historical artifacts. Their technical expertise lies in creating structurally sound, non-invasive mounting systems that accommodate complex textile configurations, fragile garments, and three-dimensional costume elements, ensuring both visual presentation and long-term preservation. The company’s key differentiator is its deep understanding of museum conservation standards, combining traditional tailoring and millinery techniques with engineered support systems that minimize stress on historic textiles while enabling dynamic, visitor-accessible displays. The contractor maintains a consistent, high-trust relationship with the Smithsonian Institution, delivering mission-critical mounting solutions for seasonal exhibition cycles. Their work supports the Institution’s curatorial goals by enabling the rotation and presentation of sensitive artifacts in climate-controlled environments, demonstrating an established rapport with museum conservators and exhibition designers who require exacting standards of handling and display. JLN Costume Mounting LLC operates primarily under NAICS 238390, which encompasses specialized building finishing services tailored to institutional interiors—here applied to exhibit fabrication rather than architectural finishes. This places them at the intersection of cultural heritage infrastructure and fine craftsmanship, serving a niche vertical within the museum and heritage sector that demands artisanal precision and material science knowledge. As a Women-Owned Small Business and Woman-Owned Business certified entity, the company is positioned within the federal government’s diversity procurement programs. Based in Philadelphia, Pennsylvania, JLN Costume Mounting LLC brings localized expertise to national cultural institutions, combining agile, small-business responsiveness with the technical rigor required for high-stakes museum installations.
