So I've been looking for this particular cover version of Sherlock Holmes, but couldn't find it anywhere. So I decided I'll get the print from online sources and print the cover myself. But again problems arise, I haven't done this before and making a cover seems difficult. The cover I want has white margins too and is a dust jacket paperback. Can anyone help me out in this? I really want to pursue custom cover making as a hobby but I don't know where to start and what to do.
