Texture is a very important element of design and one of my favorites. There are so many things you can do with texture to put extra flair in your wedding. Decide what kind of feel you want your wedding to have. Then find images of textures that represent that feeling. For instance, here are some pictures for a soft wedding.
Here are some images with an earthy feeling. I love twig weddings.
And here is a sophisticated wedding, full of crystal.
Play around with different textures that fit your theme and see which you like best. Your theme texture could be shiny or soft or comfortable or organic or rough. There are endless ideas and it can be a lot of fun finding items with just the right texture for your wedding.
