My first layout using Affinity Photo https://the-lilypad.com/forum/galleries/royal-memories.431453/
Layout done using Affinity Publisher with Photo persona linked in - much easier than using Photo on it's own. https://the-lilypad.com/forum/galleries/psalm-24.431470/
I do like the "pre-flight checks" function in Affinity Publisher. When I exported the page I was working on it told me I had spelt something wrong, and had text outside my text box, and suggested fixing it before exporting the document. It also mentioned potential bleed issues which I didn't understand.
