Use an old bike tube to make a tools belt.
Step 1: What You Need.
You will need an used bike tube, some duct tape and a pair of scissors.
Step 2: Cut
Cut a long part of the tube, according to how long you want the belt to be.
From the remaining part, cut 3 pieces of about 15 cm.
Cut the rest of the tube in small rings shape (as many as you want).
Step 3: The Buckle
On one end of the tube make a small cut, big enough for the other end to pass through.
Afterwards you can make a knot to fasten it.
Notice the position of the small pieces of the tube and of the rings. There they should be attached to the belt.
Step 4: The Pokets
Use duct tape to attach the 15 cm pieces to the belt.
Run a piece of duct tape through the small tube and fasten it to the belt.
Step 5: The Bottom
Use some more duct tape to make the bottom of the pockets.
Step 6: The Rings
From the pockets to the other end of the belt attach the rubber rings using duct tape.
Step 7: The End
This is how it looks like full with tools.
You can add some stickers to personalize it.
