These mudguards are small enough to keep in the bottom of your bag for whenever you may need them AND this whole instructable cost me only £1!!!
Step 1: Find your material!
Step 2: Mark out the rear mudguard
Step 3: Hole punch and score
I chose to score a line down the middle of the mudguard on the top side. This scored line will allow the plastic to flex upwards much like a conventional mudguard.
Step 4: Mark out and cut the front mudguard
Make two holes and link them with a single slit. The rubber band will loop through these holes and over the frame.
Step 5: Clip the pieces in place
Step 6: Take them for a spin
Print the stencil at A4 size.
Step 7: The good people from Ass Savers have been in touch!
This instructable is basically an adaptation of the Ass Saver (http://ass-savers.com). The good people at Ass Saver have kindly offered us the original ass saver template and even recommended the perfect plastic to use. They recommend using the plastic that comes from flexible document folders (as pictured). Help yourself to the PDF copy of their brilliant template.
I had to use these myself recently when it started raining whilst I was at work. Luckily a plastic folder was close to hand!
