I make homemade wrapping paper from magazine & catalog photography. I get old issues of magazines printed on good paper like Martha Stewart & Real Simple, and catalogs like Bergdorf Goodman, Pottery Barn, and Anthropologie from coworkers/the recycle bin at work, or by requesting them on Freecycle & Craigslist.
I tear out full-page photos of fashion/nature/home/food photography (nothing with words or advertising) and group them either by color or by item--mainly green-hued pages together, or all food pics together, etc--then use rubber cement to paste the pages together.
Sometimes I make a bunch of wrapping paper in advance and keep it secured around an old wrapping paper tube with a hair elastic; sometimes I make it on an as-needed basis from stacks of pages that I have torn out and put into folders based on color or object.
Other bonus: as I'm going through tearing up the magazines, I also pull out recipes or other ideas to try and stash them in binders for recipe ideas and projects around the house.
