Not my favorite task, but a very needed one.
After all of the editing and beta readers, it's taking one last look at my book with cover and formatting and checking those small errors that always seem to make it in the final proof.
Front cover and back cover once over
Commas in strange places or no commas where there should be commas
Centering of chapter headings (even forgotten chapter headings. I've got one of those this time. No once caught it!
Quotation marks in the wrong places or no quotation marks where there should be quotations marks
Awkward sentences that no one else spotted
And so it goes...
Happy Writing! (and editing!)
