I now use Affinity Publisher for all of my print book formatting as well as my advertisements and book covers. Previously I used Word for non-fiction print formatting, Vellum for novels, and GIMP for any advertisements or covers.
It’s a great tool and I think they have excellent user forums and learning videos on their website (https://affinity.serif.com/en-us/), but for me when I was learning how to use the program, the content wasn’t in an order that made sense for what I needed. So I did a lot of watching and drowning and then finally putting it all together at the end.
To save others who may not be graphic designers but are instead self-publishers looking to master a new tool that same experience, I wrote books summarizing what I learned and, in some cases, also put together video courses.
Affinity released a new version, 2.0, in late 2022. So if you just bought the program, then you’ll want one of these books:
If you’ve had the program for a while, chances are you have the original version of the program, in which case you will want one of the books or video courses below.
If you have 2.0 you could still use one of the books or video courses below, because the mechanics of things haven’t really changed, but the appearance of the program has and a few things did move around so there’d be a bit of adjustment you’d need to make.
