I have been wanting to paint my own lampshades for many years. Please watch this fascinating video on painting and making your own lampshade. I do not have a supplier of the lampshade materials. I can see that Glen is using Dupont dyes. I use Jacquard Red label and Tinfix dyes, but all are pretty comparable. None of these are light fast so it is very important that only incandescent or the new LED non UV or IR light bulbs be used in the lamp, all other bulbs have UV rays and will fade the dyes.
