A neat book about craftcycling, upcycling - call it what you want, and I don't mind it's a trendy topic. :)
The book is written for kids as the main target audience, but there are a lot of ideas for adults too. Browse, get some ideas, and the next time you were rushing to buy something new, instead make something of the junk materials you already had home. Like an empty milk box or carton, old cans, the mountains of junk mail...
