How Do I add textured backgrounds to a Pages project?

Welcome to the forums!

To add a texture to a page, you simply create an object with that texture, resize it to fit the page, and the using the Arrange menu choose "Send Object to Background". Alternatively, if you want the texture across a number of pages, instead of sending the object to the background, you can put it on the section master (using Format > Advanced > Move Object to Section Master).

A word of warning, if you are thinking of using a tiled texture fill for a rectangular shape your tile will default to 72dpi, regardless of what it was set to in the program that created it.

Creating a page-sized pattern or fill to use as a background graphic may result in a much larger file than expected.

Tulse, "Move Object to Section Master" doesn't work in page layout mode, only word processing modem, as page layout mode doesn't support sections. Which makes me realize page layout mode, not word processing mode, is the new mode.

If you Google "textures" you will get many sites that offer free textures.
