The resource is in this case the National Geographic magazine. It provides great maps I want to save. Sometimes they happen not be be very interesting to me but always have a great look and composition so they make a great source for wrapping paper. I just have to find out the one I don't want to save.
Step 2: Wrap up
You probably do not need instructions on how to wrap your Christmas gifts. Only want to add that Nat Geo maps are great for wrapping books I read during my daily commute so as not to wear out their real cover.
This seems to attract attention also...
