Oh, how much some people -- myself included -- love browsing for beautiful new diaries. The Eco Clip encourages you to curb that consumerist habit since the materials for making your own blank booklet can likely be found in your own home. IGLOO Design has dreamed up this simple spine of about 9 inches long, requiring you to obtain your paper from the recycling bin, old scratch pads or from some (ideally) sustainable source for new sheets.
Gather together up to 15 pages of A4 dimensions and fold the stack in half. Slide the creased edge down the length of the Eco Clip. A bar down its core keeps them fixed in place from the centerfold and the external pinching edges give you a secure binder for whatever purpose you desire it.
