Every sporran I have come across was more than roomy enough to hold lots of stuff. I never imagined any man saying that his sporran was too small. How large are these Italian personal ID documents? I would suggest just shopping around a bit to find a large enough sporran. You can also make your own basic one. The pattern is quite simple.

A quick Google search yielded this link: http://members.aol.com/randwhit/patterns.htm#pouch My dad and I have made several over the years, we just made the pattern up ourselves or reversed-engineered existing ones.

Yes, and the Sporganiser is an awesome idea. It will keep ya from losing stuff in your sporran when you do find a big one.
