For my daughter's 8th birthday we came up with an "recycled art" birthday party, combining two of her loves, being green + art. You can see more party details here. Here is a tutorial on how to make the favors we handed out--they were a hit...
Recycled Party Favors
1. Cut out 3 rectangles of fused plastic. One 9 x 7.5 inches (cover), one 5 x 9 inches (pocket) and one 4 x 1.5 inches (tab).
2. Center the tab on the short side of the outside cover, hold in place (you don't want to use pins...the holes will stay). Stitch with the needle positioned to the right all the way around the tab. Then stitch across the the tab to reinforce; move your needle back to center (whatever design you want...stripes..a "X"...)
