I have an image that is small and would like to continue out it's background on a much larger area, without enlarging the inside image itself. Is there a way to due this seamlessly in elements without using the cloning or sponging tool?
You could use part of the background to define a pattern and then use the pattern stamp tool which is nested with the clone tool. Right click on the tool or keep pressing the S key to tab. http://help.adobe.com/en_US/photoshopelements/using/WS287f927bd30d4b1f 71abaa0b12e28aec742-7fdb.html
Have more information now.
After you have enlarged the canvas sufficiently, make a selection of wall with the rectangular marquee tool. Put the selection on its own layer, use the move tool to position the selection. Do this for other areas of the expanded canvas as well. Use the clone tool only to tidy up, i.e. sparingly, and do the cloning on a blank layer at the top of the stack of layers in the layers palette.That way you can adjust the opacity and blending mode.
See this discussion for using the Recompose tool:
