Hair down question

This may sound dumb, but where do you put your veil?

For example, if I were to have a cathedral veil (which I would like), and a blusher and a veil to wear during the reception, do I need 3 different veils and change them?

Oh boy!

You'd wear them on the top of your head, waterfall style.

You would get a 2 tier-elbow or fingertip length veil with a detachable (velcro is one option) cathedral. You would wear both to your ceremony and use the top tier of the 2 tier as your blusher (or get a detachable blusher also). Then, later you'd remove the cathedral (and blusher if you decided to get a separate one) and just wear the the 2-tier for the reception. This is basically what I did.

Another option is to leave all the veils on and bustle the cathedral with your gown.
