Indigo dyeing
Indigo is a unique process and requires different processes than other dyes to be successful. See our instructions for different types of indigo vats below!
Indigo Instructions
Our indigo instructions originally used a recipe based on Michel Garcia’s 1-2-3 vat, created nearly 10 years ago. Since then, we’ve made some changes and developed different recipes that will allow you to control how light or dark your vat is. Types of Vats: There are three main types of vats that you can build. Use the indigo instructions below to decide which one is best for you. Vat type About Advantages Disadvantages Fructose Clearest blue Dyes lighter than henna or iron Seems to perform best when aged for 2-3 days, and when warmed before use.

Hide Glue Indigo Vat Instructions

How to Make a 1-2-3 Henna Indigo Vat
A henna vat will give you a warm blue color as henna has a strong brown-orange undertone, and it influences the cool shades of blue. It is a good choice for dark blue shades. Henna vats get noticeably stronger after several days of rest once they are built and the vat will smell strongly herbal. The henna powder is quite bulky and goopy when it is hydrated, so we like to mix it separately with a generous amount of water and then strain it through a fine mesh sieve to remove any lumps before adding it into the vat. Unsure … Read more
How to Make a 1-2-3 Iron Indigo Vat
An iron vat will give you a cool blue-gray color. It is a good choice for dark blue shades. Once it is built, you can dip in this vat at room temperature without reheating it. If you want to dye wool or silk, do not use an iron vat as it damages protein fibers. Important safety note: Iron (ferrous sulfate) in high doses is unsafe for babies, small children and pets. It is not known if iron residue remains on the fabric and in the vat in amounts that could be of concern. Out of an abundance of caution, we … Read more
