It requires very minimal artistic skills, with professional looking results. (Can't go wrong!)
And hey, it's a step up from merely tossing the paper in your recycle bin! You might actually get a nice piece of art out of it.
Here's a list of all you need to begin:
-your canvas (doesn't have to be anything fancy, a piece of cardstock does the job)
-your glue (again, simple is ideal: go for the glue stick)
-pencil or pen
And, most importantly: your materials to recycle.
Magazines and catologues are recommended, since the paper is thin and tears easily.
Step 1: Creating your guide
Label your sections with the colors or color schemes that you want to fill them with. This way, when you search for strips, you will have an idea of what to look for.
