Over 35 years ago, Rupert, Gibbon & Spider was incorporated by the Katz family as a distributor for Deka products and business was conducted out of the garage. The company transformed when President, Michael Katz, began manufacturing his own art supplies under the brand name “Jacquard Products” in the late 1980’s. Inspired by the silk-painting craze of the time (silk was hot in the ‘80’s!), Katz introduced Red Label Silk Colors as Jacquard’s first product. To this day, they remain a staple of professional silk painters everywhere. This initial success invigorated Jacquard Products to produce more textile artist materials. New products have consistently been introduced every year, and now Jacquard offers over 20 product lines as well as a wide variety of kits, sets, class packs, chemicals and other art-related auxiliaries. Over the years, Jacquard has built a reputation for innovation and high-quality products. Michael Katz announced his retirement, in 2012, and his son Asher began running the company. Like his father, Asher is involved in every aspect of the business, from research and development to sales and marketing. Jacquard Products are sold in art and craft stores all over the world. Jacquard remains as committed as ever to meeting the needs of artists and crafters everywhere with excellence and value.
