Drawstring Bag - Gallnut Extract

Lightweight and versatile drawstring bag dyed with gallnut extract and modified with iron.

 

Gallnuts are irregular growths caused by insects and can be found on oak and sumac trees. They are incredibly high in tannins and can be used to introduce tannins to a fabric without leaving color. When modified with iron, fabric treated with gallnuts turns a dark blue. 

 

Material: 100% Cotton
