Finally - this is so long overdue, I wrote a post about this project ages ago and I have been using this bag for months and I kept forgetting to photograph it, but I must say it is probably the most useful bag I have ever had - it is just the right size and yet I can fit so much in it without it breaking my shoulder, and the studs protect it from all the nastiness on the floor when you put it down.
It is incredibly easy to attach the studs, all you need to do is plot where your studs will go, and then measure and punch the holes in the leather base with a thick needle or scalpel and push the prongs on the back through the holes, then use a pair of pliers or something solid to push down the prongs so they lie flush with the base of the bag, and you are ready to go!
If you like you could also make an insert for the base of the bag from a piece of thick card covered with a fabric sleeve, to cover the prongs inside and give it a bit more structure.
