My #1 recommendation is to buy Paul Long's sheath videos... definitely worth owning!!!
In the past I used 7-8 oz. about 95% of the time. But now I find myself making many of my sheaths from several layers of thinner leather.
The last few bowie sheaths I have made had a front that was made of 2 pieces of 2-3 oz. glued flesh side to flesh side (so you have finished leather inside and out), a piece of 10 oz. for the welt (I skived it to the exact thickness I wanted), and a back made the same as the front. And I like 2 oz. for doing chevrons on the front of the sheath.
I used alcohol based dye for many years, but have switched to oil based Fiebings and MUCH prefer it.
All the leather I have ever used came from Muir McDonald or Tandy, but the next leather I order will be from Wickett & Craig.
Definitely, his videos are very good.
Have a look in the sheathmaker secretion, lots of info there
