Textures in Photoshop
Played around with a few textures in photoshop, although the images that i took are too small for an A2 size. But have found some very large images from google luckily (A3 size), which is ok... but have to duplicate them in order to fit the actual size of my posters. Here are some screenshots of different blending modes using the texture that i had selected that thought was most suitable.
