Thanks for the replies and comments, I have been watching Leodis and Armitage, I just need to work on keeping my chisel straight when punching the holes.
In regards to waxed thread - I don't have any right now, but I've been using a block of Beeswax and running the thread through it to coat it for the first project, forgot on the second too, so I'll make sure I do until I get some waxed thread.
Never thought of slicking the flesh side, I don't have that gum, I've just been burnishing with saddle soap and water then finishing with beeswax.
