Thrift Store DIY Panniers
From Problem Solvers sage customer serviceman Gage:
"You can buy cheap manageable sized tote-bags from thrift stores and easily convert them to stylish panniers, I have done so using sheet PVC plastic and random hardware from the garage.
Thrift store tote bag...
Cutting PVC to fit inside the tote bag. This gives a stiff surface to hold the shape of the bag, as well as a strong enough surface for attaching hardware.
Some random hardware bits from the garage. Ideally, something bendable. Think old rack struts, p-clamps, etc.
Bend two straps in to "J" shapes
Attach the "J" shaped hooks to the PVC through the bag. An old inner tube makes a nice elastic strap to keep the bag secure to the rack.
Inside the bag view; note hardware attachment.
The bag attached
About 45 minutes later, you've got yourself a solid pannier for mostly free!
