Grain Growing & Cooking Chat (Example)

Example post for the hub walkthrough. Not a real member post.

We've been trying to thresh button grass seed by hand: rubbing the seed heads on a rubber mat, then winnowing in front of a fan. The seed is small and smooth, so soil grains of the same size end up mixed in, and it takes a few passes through a fine sieve to clean.

What setups have worked for you? Sieve sizes, mats or small machines all welcome.
