Have you ever found yourself in need of a way to carry stuff on a bike when you don't have a carrier? A plastic grocery bag isn't a great solution - it is unbalanced and can bang around and get in the way. Furoshiki to the rescue! A Furoshiki is a Japanese wrapping cloth. They are very useful and eco-friendly. Any squarish piece of fabric with a finished edge can be a furoshiki. The size you use depends on how you are using it. Most people have at least one bandanna around the house, so that is what I am using in this instructable.
Step 1: Lay it out
Lay your bandanna out flat. For the purpose of this instructable, we'll call the top two corners A and B, and the bottom two C and D.
Step 2: First knot
Tie corners A and B together in a square or double knot as close to the corners as possible. Pull it as tight as you can.
Step 3: Put it on the bike
Slide the knotted end over a handlebar. Sliding the knot as close to the center as you can makes it easier to tie the second knot.
Step 4: The second knot
Bring corners C and D up on either side of the other handlebar, then tie them in a square or double knot.
Step 5: Tah-dah!
Now you have a carrier for your bike! A standard bandanna is about 22"x22", so it makes a fairly small carrier. I usually use an oversized bandanna, about 27"x27".
