Looks good to me!
Any tips for a 1st timer then? I'm assuming the nose is the most difficult part?
I used these instructions as a guide:http://www.instructables.com/id/How-to- ... ycle-seat/
I didn't use staples as it suggests. I found that just using a good spray contact adhesive works well and is less unsightly.
Take care removing the old leather as it will probably be stuck hard to the foam which you can use again. I used a Stanley knife blade to shave the leather off the foam.
Stretching the leather around the nose you'll find that there is a lot of exces leather that gathers up - keep stretching.
Best of luck. It would be good to see a photo when you are done.
Too many bikes and still too few
