Don't mean to hijack a thread, but this seemed the right one to ask a mudflap question.
Would anybody buy leather mudflaps? Maybe not, because home-made is the epitome of cheap and recycled.
However, I know an 85 year old disabled man who occupies his time with small projects. He made me two sets from different patterns. He can add layers of leather for more or less "flappiness" or insert a plastic mid-layer for a firmer mudflap. The flaps are NOT made from thick cowhide like a Brooks saddle.
Apologies if this question is out of line in any way.
