Easy-Weave Newsprint Basket -- not these baskets, but I'm thinking about the prospect of framing an entire children's grade of one project in newspaper. Like newspaper for the mat, and then construction paper for the frame.
Made these out paper they turned out amazing, I like how they used all different sizes. A twist on the poms. 20 Paper circles with an equilateral triangle in the middle. Fold along triangle and glue together edges. Nice for Christmas decorations, too.
Collect your neighborhood's plastic water bottles and turn them into a chandelier with help from Oh Happy Day. Then sit below it while you enjoy a refreshing drink from a glass or reusable water bottle.
