There are some of the best challenges over at Moxie Fab World
Like this one called Don't Throw it Away!
That is me! I save packaging, boxes, all sorts of things wondering how I might put them to use.
For example, I saved this plastic package from a punch. And here I used it on a card. I cute circles and then used my heat gun to kind of melt them into flowers. It is a fun technique and they look very unusual.
