Pickling onions?

[kt.]

Some of my onions are small this year so I intend to pickle them.  Do they need to be blanched at all or can I just add the pickling vinegar?  Also, how long will they need to ferment before being ready to eat?

Hi
 When i do my shallots i soak them in salt water overnight good rinse in the morning then add a spoon full of sugar to the jar with the pickling vinegar,  But i have allso  done what you say peel in the jar + vinegar, there ok more of a crunch i find, Depends on your own taste ;)

I try to leave them at least one month before eating ;) but longer is better..

we always soak ours in brine overnight like steve76 but sometimes instead of sugar I've put in a whole chilli  :)
