Re: Tinsmith's saddle how to...
Next I tacked the two pieces of leather together seeing that the bottom piece stayed flat to the bottom and the top piece came down over the side of the seat. At several points I used the awl to make two holes so that I could tie the top and bottom together with sinew. Once tacked together into the general shape of the seat, I used two harness needles with one long piece of thread... each needle is toward an end of the thread.
Now I make holes with the awl as I go around the saddle. Each needle passes through the same hole, one from under and the other from above. Keep going until you've made it all around, tie it off and burn the end of the sinew (a thick synthetic thread which is used in place of real sinew) and mash it while still hot... now it can never come untied.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
