Rose Brand's Weave A bobbinette has the typical hex shaped opening expected in most bobbinettes. The Weave A opening is smaller than the hex opening of our Weave B bobbinette. Bobbinettes have a more open weave than Sharkstooth Scrim or Square Gauze. These various weaves give designers a range of light transmission values to create depth, and to give a soft & hazy look to images. Bobbinettes are often used in combination with Sharkstooth Scrims, or in front of rear projection screens to reduce glare and increase contrast. Note, 10' can vary from 9’6" to 10'. Approximately 5 holes per inch vertically (0.4 cm each).
