”Sheep Poo Paper is derived from just where the name implies and is available in a wide range of colors, sizes and thicknesses. It is a viable alternative to tree-based paper, but comes from a renewable, less energy intensive source. Used for everyday paper stock, heavier card stock, envelopes, business cards, post and gift cards and custom orders and designs. The sheep poo that is collected is completely sterilized by boiling and is then beaten into a cellulose pulp. Using traditional techniques, the pulp is formed into sheets and heat pressed into usable paper.” [via jgebbia on Twitter]
