I dyed this after I wove it. The warp is alternating natural & EZ Dye cotton. I dyed the ends of the warp in pokeberry juice to make sure I had the threading order correct, since it is very hard to distinguish it from the natural. The EZ Dye holds the pokeberry, but it washes right out of the natural.I pasted a note on my loom that said "even = color" in case I broke a thread or left off for a week and couldn't remember which was where. I tied a colored string around the pirn that held the EZ Dye yarn. My suggestion if you want to try this color play on spot bronson with the EZ Dye cotton is to alternate with black instead of natural, or with bleached white so the color difference is distinct.
For the finished pieces, I dyed the cloth in marigolds from my front yard. The marigold tinted the natural yarn a very pale yellow.
I did the sampler shown in the draft images in direct dyes. Note the direct dyes tint the natural cotton a light color while they dye the EZ Dye a dark color.
