Afternoon all, 
I am starting to do my own hoof work for my horses and have always loved leatherwork and the art of.  I want to make my own leather chaps or chinks for my venture into farrier work.  I see that Tandy offers chap patterns.  I do not know if I need the length of chaps or chinks for this work.  Then I am not sure what weight or type of leather to invest in for my project or where to go for my supplies.  Any help would be most appreciated. 
Thanks 
Sid
