Trashy Beach Art: update

My project is well on its way, however I keep needing more plastic. I have picked up two grocery bags full so far, but I still don't have enough. Then again I tend to pick up plastic/trash regardless of its color...so this next trash run I'll have to be a little picky.

Needs:

* beach trash (blue/green)
* hot glue sticks (a lot!)
* time (we are moving in a week!)
* black piece of fabric/bed sheet
