I've been a little preoccupied lately, but I did manage to make some black swallow-wort paper. It was made from a batch I collected on the MSU campus - thanks to Frank Telewski. It came out too dark at first, so I lightened it with bleach.
Unfortunately, it's not taking ink transfers, so it won't be making an appearance in the Foreshadowing series. However, it does make beautiful paper!
