Well, I am famous for answering questions people did not ask....and sometimes did not want to know... but why stop now ?
There are only two good edge treatments that I know of. A slicked edge like a belt usually gets....and the standard Double Cordovan Stitch. Other treatments either look cheap ( single loop ) or don't hide and finish the edge or take the risk of overpowering the piece....like Triple Cordovan ( which also uses an incredible amount of expensive lace to cover the same edge that the Double Cordovan will cover just fine.
Tom Hall spent several days here at the house visiting with my father a while back... and in learing enough to help out at the braiding class he was giving at the local Tandy store I learned a couple of things I had not picked up before...
One, serious braiding people skive the edges of the lace. There are little machines which can do this... but Tom used masking tape to secure a single edge razor blade to his hand while I walked backwards pulling the lace... amazing... when doing Turks heads and fancy stuff like that it really makes the piece look neat to not have the edges showing...
Two, lubricate your lace before using... either white saddle soap ... or neutral shoe polish... the lace will be the first part of your project to dry out anyway.... and for braiding it allows you to pull it tight and then when it dries some be even tighter....
Warning.... you do NOT pull normal Double Cordovan lacing tight on billfolds, etc... you just ' lay it up' ... taking the space out.... but decidedly loose... then when you finish you take a mallet and gently flatten it by tapping in the same plane as the face of your project...
The book by Tandy called " Lucky Seven photocarve patterns " which has 7 billford patterns has the standard Double Cordovan instruction on page 14 and 15.
However, I always suggest the use of the " hook and eye" lacing needle ( just gently push the hook in with your hammer handle .. don't smash it... I have some over 10 years old ) ...
And I suggest the alternate ending procedure shown in figure 15 on page 15 ... taking the end down between the pieces of leather... with very little practice no one will be able to see where you start and finish... Greg
