1. I would agree with Tobus as well. However, it does take a bit of practice and if you need sweep instructions, ask the females in your life - they know. If you are a gentleman of substance, the knees together suggestion is impractical and uncomfortable.

2. If you intend to dress formally, you probably need two sporrans (see Nathan's post). If I could only have one, it would probably be a chrome-cantled black hunting sporran.

3. Although there are lots here that are dead set against chain-link sporran straps and warn against apron wear, I have a good quality one and have not had a problem. That having been said, I generally use a leather sporran strap and I occasionally use hangers (see gentleman of substance reference above).
