To no surprise, this is paper made by hand.  The way this is done is by using a "mould" - basically a frame with is covered with a flat rigit screen (western) or flexible screen (asian).  In both cases, the mould is covered by a flat frame (called a deckle) to contain the run-off of wet pulp, dipped into a vat of wet pulp, shaken to distribute the fibers evenly and drained of its excess water.  

The wet mat of fibers remaining is the newly formed sheet, which is then air dried.

Handmade papermaking can be a totally manual process, involving no electricity.  Handmade papers are one-of-a-kind and have four deckle edges.

There's a great (longer) description here as well.
