Do you need to buy a Thermofax machine to take the course?
Absolutely not. There are many people who offer pre-made designs and as well produce custom screens from your artwork for such a low cost it really isn’t necessary to buy and maintain a machine. Either way, the workshop explores both producing your own screens from scratch as well as developing personal imagery for your work.
Do I need to understand color mixing or how to prepare anything to begin?
Everything you need is covered in the workshop. Dye recipes as well as how to make everything from Chemical Water to Print Paste is reviewed both in the video and in the written portion.
