Well, I have managed to use synthetic dyes completely unsupervised in my own house. It’s taken me at least 20 years to get up the nerve and confidence to do this. I know…. there has never been a logical reason for this, but it’s been a huge hurdle for me to attempt this at home!
I sectioned off about 1/2″ of warp at both selvedges to paint a solid color with the burnt orange. And then I sectioned off an inch to paint in a pseudo-ikat effect. Each of these sections was wrapped in it’s own bit of cling wrap to prevent any co-mingling of colors. Finally, I painted the main, center section.
After a curing period of about 6 hours wrapped in plastic, I uncovered the warp to let it dry. The far end of the warp is now suspended off the table for better air circulation.
