Molly, I use Affinty Designer to make my comics. I am using Affinity Publisher to layout the books and create the final pdf. Affinity make great, professional-level software for a great price. No subscription needed.
I will use Lulu. com for printing my books. I have been publishing my own guitar method books using Lulu for over 10 years, so I know how it works. I may do print copies using Amazon also. I haven’t used Amazon for print so I will have some learning to do if I use them also.
I am using iBooks Author to make the eBooks.
I don’t expect big sales (if any.) I just wanted to have a few copies of my own and make them available for anyone is interested in a copy.
