Message: In my workplace, we have audio panels, covered in 100% polyester fabric.  The panels are too light and are reflecting too much light in our production studio, so we need to dye them black.  Do you think the crayon dyeing method would work for us?

The crayon method will work for darkening your polyester panels in patches. Is it okay if they have a patchy look? It will not work for producing a smooth even color.

Less labor will be required if you buy disperse dye powder from PRO Chemical & Dye and use it to mix up black paint to apply wet to paper, to use to iron on in the same way as the crayons. It is really quite a lot of work to hand-color a large expanse of paper! The coloring may be less patchy looking, as well, when you use the paints, though the iron-on process seems unlikely to ever yield a single smooth tone.

You will presumably have to remove the panels from their backing in order to iron the disperse dye onto them. Perhaps you should just purchase similar fabric in black and use that to replace the existing fabric.
