Woad Seeds - Dried and Ground

Woad (Seeds) - Ground

1. Collect some woad seeds.
2. Allow these seeds time to dry.
3. Using a pestle and mortar grind the dried woad seeds.
4. Grind and sieve the woad seeds until a suitable micron size is found. (Anything under 100 microns) (a strong blue is made, this can also be used as a dye or can be used in the production of lakes) (Maybe adding egg shell white will create a really strong light blue?)
