Hi Karen, thanks for reaching out! And so cool to see we share a love of breathwork. What technique(s) do you breathe?
Thats cool to hear that others are sharing this info too as its a real possibility! Do you have a topic in mind that you'd like to turn into a book?

For the canonical links and anything else related to your blog posts (photos, affiliate links, summaries, re-caps etc...) reformat those aspects to make your book(s) flow as books. Adpat each blog post to become a chapter of a book that flows together. You can add a few extra paragraphs to expand on each chatper or simply just a line or two at the end or beginning of each chapter.
I hope that helps!
