I really enjoy enhancing my images by adding textures, nearly all the images in my 'Canada's Atlantic Provinces' book have had textures added to give them a more story book/vintage feel. My ongoing 'Dreamy Nature' collection are also texutured lightly to create a slightly softer feel to them.
I have put together an easy 6 step tutorial that you might like to follow if you are new to textures. Also included with the tutorial is a free texture created by me and used in the the example image here. I would be most grateful if you use the texture if you would credit me and kindly link back to this blog so that others can use it too. Click here to download the zipped file.
If you are feeling more adventurous and fancy having a go at creating your own textures from scatch in Photoshop, then here's a great little tutorial for making paper textures.
