Paper is a passion of Bavaria's Hilli Zenz... she enjoys origami, kirigami, bookbinding, and paper marbling. In fact, Hilli used her own hand-marbled paper (it looks like watered silk to me!) to make this folded nautilus (or snail perhaps), following Tomoko Fuse's online instructions from his Scribd book, Spirals, Shells, Boxes, Snails.
See many more of Hilli's beautiful creations on her Flickrstream.
Have a great weekend - I hope you have something fun planned.
