When all the sewing is completed, the indigo will re-commence. It is important to dye each completed outfit at the same time so that the shades of indigo more or less match. The vat will weaken over time. The vat also does not like cool weather, so speed is of the essence here. Autumn is upon us. I prefer to do the indigo dyeing in the yard...but will bring the stinking mess into the studio if necessary. Drop clothes will protect most of the space. And, once it oxidizes it does smell of flowers rather than urine!
