My latest Trashmagination obsession is weaving plastic bags into colorful mats on my floor loom. This project has reinforced three Trashmagination ideas:
1) When you learn how to make things with non-trash materials, chances are high that you can use trash materials instead.
2) Ask for help and trust the universe will bring you what you need.
3) You don't have to know exactly how something will turn out before you get started.
