Speaking as a museum professional and a living history practitioner, what a great project.
At the Los Angeles County Museum of Art’s web page, conservators and curators worked with Thomas John Bernard, a theatrical designer, to create gridded patterns of four eighteenth century men’s garments, offered online at no charge. This effort both shares the construction information of four extant garments as well as reveals the museum at work. Those of us who are collection managers know that all our preservation efforts are only as good as the access to collections that preservation affords. If providing patterns of these objects online reduces the need for handling by some researchers, then progress in the preservation of that object has been made. Certainly, costs involved included time spent working with the objects, drawing the patterns, dressing the objects and photographing them (perhaps done in the past for another exhibition), and web development. But creating and sharing these patterns and notes online shares the knowledge acquired during one researchers visit, multiplying the impact of that session.
