I got the good price of cotton gauze and keen to try natural dyes on it without hesitation. The blue-grey was dyed from indigo while the pink-purple from cochinael.
I was asked to recommend reference books for my natural prints. There're many experts doing great but my answer to my works is my "brain". It's joking but truely I appreciate very much other experts but I can't follow well because of local condition, such as water, soil, air, plants, weather...... all depends, that's very regionalism. So I can only recall my own experiments and explore any possibilities.
This blue-grey from kind of indigo, the plant is Strobilantes ( 馬藍) from my yard. I only used the simply way to get the pigments. Know this may not be the proper way but it works for me.
I chopped the leaves, soaked in a jar with warm water for two days, mixed with little lime and pour into a container for a few times to get oxygen for darker blue-grey. Then soaked the cotton gauze for a few minutes.
The shades of colors due to the amount of soaking time . The bolder the first time.
I wanted purple from cochinael
So I dipped into the dyes
This is how I made the cold cochinael. I grated a little cochinael and mixed with alum and water, as well a little vinegar. Let it sit for a couple of hours.
So I dyed a few yards of cotton gauze with indigo and cochinael in cold way.
