"Did anybody else do that?"
Yeah I did that. At the time I was working in IT at a College gfx / 3d model etc dept who had one of the newfangled Colour Laser printers worth about £50k , So i could print out front and back for 3 cd jewel cases on an A3 sheet.
So i still have a couple racks of painstakingly recreated , worthless , CDRs staring at me at home. Not been touched for years , taking up space , daring me to throw them away ..
