As you know, I love paper stuff. These new 2D puzzles designed by Ingela Arrhenius for OMM Design are my kinda toy - fun, cheerful and made from card. I can't wait for them to hit the shops.
If you're into paper craft too, why not turn to sites like etsy for some original, vintage finds? A quick search yesterday produced this similar set of Notch-em die-cut animals, which although not complete is cute, cheap and has great retro appeal.
