When sourcing conference cloth, the fabric weight (GSM) is a primary indicator of quality; for professional settings, aim for 200-280 GSM to ensure a premium drape and opacity. Additionally, verify the material composition, typically a blend of Polyester and Spandex (90/10 or 95/5) for stretchable covers, or 100% treated Polyester for traditional throws. Ensure the fabric features wrinkle-resistant properties and reinforced stitching at the edges to prevent fraying during frequent setup and teardown.
