Thanks.

The front fender is a standard cheapo black plastic fender ziptied on (except I think it's an old rear fender, no matter), but the end behind the front wheel was a bit short to protect the bottom bracket. So I cut a large plastic soda bottle roughly in half lengthwise and cut off the bottom and the top, so I had a curved piece of plastic maybe 15 cm long. Punched a couple of holes near the corners in one end, a couple of holes in the end of the fender, over lapped and ziptied together. I know, I should go out and take a picture instead but it's dark and I'm lazy
