I started with a square wood frame and glued textured items to it - die cut chipboard letters, corrugated cardboard flowers, twine swirls, mesh tape and punchies. I used double sided tape to attach all the elements except the mesh tape with is self adhesive. Next, I covered all the front and the inside and outside edges with metal foil tape. Yes, the kind you buy at the hardware store!! I simply cut it into pieces and just started layering it on. Check out the photo below which I took as I was in the process of applying tape. As you can see it doesn't matter what your pieces look like because they will all be covered and you will only see their shape and texture.
Here are a few tutorials I used for inspiration:

I can see using this technique to make decorative paper for masculine cards and other projects where you want a bit of an industrial look!!
