So I design resources to help people make their own professional book cover designs easily, without spending a lot of money.
I put a lot of those tools (including free guides, free templates, a list of best fonts per genre) up at www.diybookcovers.com.
There’s even a free online cover making software.
You can download a bunch of helpful resources for free *(you need to share the page to download all the contents) – there’s also a paid option to get a big package of templates for $87, but you don’t need to buy them unless you need extra help making your book cover design.
