Basic seed saving supplies
Sieves
The thing that I most go for when cleaning seeds is my big pile of sieves. They don't have to be new, any old sieve will do. Keep an eye out when thriftng or at garage sales for cheap sieves or colanders. A wide assortment of different sizes and shapes of holes is key. Generally, we start with the biggest and work our way down until we are left with just seeds and chaff. All larger plant material like leaves and twigs are removed in this process.
