so if i were to use photoshop to make my textures would

Width-1024 pixles
Height-1024 pixles
and resolution 300 pixles per inch

be suitable for this project?

im asking because ive made flyers/leaflets in past and sent the desings of to print shop only to have them sent back because the dpi/ppi wasnt a high enough resolution.

sorry 4 the neewbe questions
your advice is much appriciated

cheers xonath
