So, I rejiggered all the covers and sent Trang and Trust back to CreateSpace--I'll know for sure when I get the new proofs back, but hopefully I took care of all the problems.
The main thing that I have to remember for Trials and Tribulations is that when I do the jacket copy, I need to adjust the font and the font box itself to get the text block to fit. If I treat it like an art element and scale it up and down to fit, the text gets really blurry.
The other interesting bit is that the bar code on the back of Trang and the bar code on the back of Trust were substantially different sizes! So that little hole I left in the cover design of Trials? It ain't there now....
