The center of this section is a piece of rust dyed cotton that I overdyed with indigo. Below that is a piece of shibori folded cotton dipped in a different indigo vat. The rust dyed piece was dyed in the iron vat and the folded piece was done in a workshop using a pre-reduced indigo and a fructose vat. I wasn't very happy with the pre-reduced indigo. The color seemed a bit flat and despite 12 dips never got that rich deep indigo that I can get with just 5 or 6 dips in the iron vat. I think the pre-reduced indigo is the issue. I feel like I get about the same results with the iron vat as from the fructose vat. I prefer the iron vat because it's easier to maintain.
