Textures are a key part of turning your simple black and white elevations or visuals into something really eye-catching and engaging. You can use textures and cut-outs for so many aspects of your work, it is worth bookmarking some of your favourite sites. The problem with textures and cutouts is that there are so many different sites offering free and paid for textures, that you can find yourself wasting hours searching for that perfect texture.
I have put together some of my favourite sites, that I tend to use often. They contain a mixture of textures, cutouts, and tillable textures which can also be really useful. Don’t forget you can add textures to your SketchUp model, and even programs such as ArchiCAD, so it is well worth collecting some of your favourite textures and putting together a library of the things that are most useful to you.
Depending on your level, and how often you use textures, sometimes it is worth purchasing a decent library. You will also find that many sites ask you to set up a free account in order to access their downloads.
Check out these sites, and download some of the textures they offer, generally for free.
Formerly CG Textures, Textures.com has a massive selection of textures, over 100,000 images! You must register for an account, then you can download 15 images per day. For more than this, or improved resolution you can set up a paid premium account.

The image below was put together really quickly from a SketchUp export of a white 3D model. By using just a few textures, you can quickly give an impression of an idea. This could obviously be taken a lot further, but as a quick photoshop render, it can be quite effective.
