hey it's BeautifulCreaturesOfLife and I was wondering how to put other people's collages 4 my background

ok so what you do first is you find the collage you want and save it to library then you go to a freestyle page on create press the plus at the bottom of the screen then press the picture with a mountain and click on the collage you wanted and then when it comes up on the page just double click on it and press set as background. hope it works text me if it doesn't.
