I am in the process of getting some lovely little Very Secret Sex Life of Medieval Women-style bookmarks. Actually, they tie in to my website and have the very encouraging words NO TOUCHY-TOUCHY on them while the lady in the bed points her finger, so they're not book merchandise as such, but they share the book cover art and manuscript leaves.
Silky coloured tassels! Pretty artwork from Tania Crossingham!
If you buy a book from me in person, you'll get one free!
