Infusions are water soluble particles with 2 components: dye colour pigment suitable for paper/ fabric mixed with Walnut stain.
The colour powder particles dissolve faster than the walnut crystals, so you can control how much colour-to-brown stain ratio you get by:
1. the amount of water you apply, and
2. when you apply water (before or after sprinkling the powders) and
3. how soon you dry the wet paper or fabric after applying water.
Blotting before drying will produce a softer result.
Make the product permanent by using with PaperArtsy glazes instead of water, or add gum arabic to the mix as another 'binding' option.
