Step 1: What You Need

For this design, you will need a...
a hook
a loom
rubber bands
'C' clips

Step 2: Placing the Rubber Bands

For this design you can also use the mini loom but I find it easier to use the Rainbow Loom.
All you need is any two arrows on the loom.

Take ONE rubber band, twist it so it's like an 8 and put it onto any two arrows on the loom.

Put TWO rubber bands on the same arrows as the one you put the 8 on.

Step 3: Starting

Take the hook and grab the twisted rubber band on the bottom and drag it onto the top.

Step 4: Hooking the Rubber Bands

Next, add another rubber band, any colour, onto the top of the other rubber band.

Step 5: Hooking the Rubber Bands

Repeat step 3. Take the bottom rubber band and drag it to the top.

Step 6: Hooking the Rubber Bands

Repeat step 4. Place another rubber band.

Step 7: Hooking the Rubber Bands

Repeat step 3. Drag the rubber band from the bottom to the top.

Step 8: Hooking the Rubber Bands

Continue doing this until you think it's long enough.

Step 9: Finishing

Now, there should only be TWO rubber bands on the arrows. Take the bottom one, for me it's white, and pull it to the top WITHOUT adding any other rubber bands.
