Ok, I'd explain more about the history of the Furoshiki method but I'll let Furoshiki.com do it.
Furoshiki is a type of traditional Japanese wrapping cloth that was frequently used to transport clothes, gifts, or other goods. Although possibly dating back as far as the Nara period, the name, meaning "bath spread", derives from the Edo period practice of using them to bundle clothes while at the sento (public baths). Before becoming associated with public baths, furoshiki was known as hiradzutsumi, or flat folded bundle. Eventually, the furoshiki's usage extended to serve as a means for merchants to transport their wares or to protect and decorate a gift.
Step 1: Cut the Sheet to Size.
Step 2: Hem the Edge.
Step 3: Now for the Folding and Tying.
2. This is kind of tricky but you'll want to take the bottom corners and bend them up towards the top of the triangle while kind of gathering the material up into a "rope" so you can tie a knot in it. Don't take all the way up to the top but just short of it.
3. Now do the same to the other side. It'll look like this.
4. The tails will be about the length.
Step 4: Flip and Shake
1. Take the top layer and peel it back then flip the whole thing over.
2. Flip the knots and tails into the center and pick up by the top and bottom corners and shake it side to side.
Step 5: Now....what Do I Put in It?
Step 6: Tie-down and Shoulder Strap.
1. Gather up the ends like this...
2. Tie them in a quick overhand knot.
3. And cinch down tight.
4. Then tie a square-knot at the very ends of the tails so it looks like this.
5. Then sling it over your shoulder and head on out there.
