Deanne Burton shows how she altered a Maya Road tin in a tutorial here.  One photo is shown below as well.  She stitched right through the clear plastic - how clever!

Angela Ward made this upcycled canvas using materials that are usually discarded or recycled.   You’ll never guess how she made the flowers! Here is what she has to say about this project, "The dark and light blue flowers are from the plastic lids of mixed nut cans - i cut them with my Big Kick and a Sizzix die, and then stamped on them.
