New Zealand poet Michele Leggott describes how her writing process has changed over the past twenty years of losing her vision. She explains that she can "project [her visual memories] into writing"; this process can give them back to her. When she talks about writing on the computer screen, relying on gigantic font, she ends with this beautiful image: "It is as if I am passing a huge magnifying glass over this language." I've enjoyed listening to her experience. You may too.
By the way, I wrote this blurb. Feel free to let me know what works, what your blurb would be. Is it even called that?
