I will be uploading ideas for the binding and covers so that you can already think about it. Just in case that you'd like to adjust some details while doing the pages.
These photos are just meant to let fly your imagination!
The "Codex Rotundus" owes its name to its round shape. It is a small book of hours (9 cm diameter) made in Bruges in 1480. Thumbnails are most likely from the workshop of Dutchman Willem Date illuminator (active from 1450 to 1482). (Hildesheim Cathedral Library, Germany)
