Good question! As someone who learned to read Braille with minimal instruction I can say that Braille is relatively easy to learn to read by sight. It is a simple system for encoding English as a series of six dots so there are no new words to learn, only a different way of representing them on the page. Each book will come with a dictionary that will help you to be able to decode the poems in the book or in the framed artworks.
Braille has a really interesting tactile qualities and a fascinating minimal visual aesthetic too - there are many ways to appreciate the poems in the book and all of these ways have fed into my composition of the works that are included.
