The Lux Fanfics

Anyone have any clue how to make good covers for books? Like, a program or photoshop or something?! Help me!!

Hey guys! So, I'm starting a new fanfic, however, I need ideas. Like, badly.. So, please tell me ideas for fanfics you wanna see, as well as who is involved! It will most likely be a ship of 5SOS or 1D. Thanks!
