Our friend "Baldman" has graciously offered to share his top-secret mudflap-making recipe, in order to up the cycle chic quotient in our beautiful world. Here's the protocol:
Find some scrap leather. He bought his for $4.95 at Tandy Leather. Cut out your mudflaps with an xacto knife.
Next cut out a stencil. He made his on a plotter, which is a machine that cuts out motifs from rolls of adhesive vinyl. Any sign shop can cut you custom letters or graphics.
I happen to know that his wife's name starts with an "A", so I bet we can work out who these flaps are for!
Attach the stencil to the flap with the adhesive vinyl sticking to the leather.
He says he just uses a standard propane blowtorch to burn the leather where the stencil reveals it. It seems that my kitchen crème brulée torch will work just fine, however this is the step you don't want to mess up!
At this point he says we want to treat them with the same proofhide that we use on a Brooks saddle. This will make them a bit more weatherproof.
OK, next step is preparing to attach them to the fenders. Punch holes in the edges of the mudflaps and string your attachment through (leather cord, hemp twine, funky yarn, whatever)
Drill holes in the bottom of your fenders to loop through:
Attach, and don't you look good!
