Lisa B1 -we have three Lisa B’s so they’re numbered- mentions a new-to-me site that may interest you (HT), that belonging to International Pleating. Fully embracing today’s demands for connectivity and transparency, they also have a blog and a FaceBook page.
In business since the 1930′s, International Pleating provides contract pleating services delivered to your specifications. They offer two types of pleating, hand (pattern pleating) and mechanical. Machine pleating ranges from knife, box, distressed and Fortuny pleating. Hand pleating types are sunburst (accordion), large box pleats and herringbone. You can see samples of each type here.
