Homemade light diffuser

When I read to students using the document camera and projector there is a glare from the fluorescent lights on the pages. If I turn off the lights I cannot see the words. Looking into the issue I found I could buy light diffusers for $35.00 per light. So I made one myself by laminating tissue paper and using double-sided duct tape to stick it to the lights. The width of the laminator is the right size (2 feet) and I ran a two four-foot lengths. The only problem is I used green and blue, so now under the lights my gray hair looks green!
