I really didnt see the point in registering 6 months in advance (like most wedding checklists suggest) especially since the showers are typically held 1-2 months before the wedding, so I just registered a couple weeks ago at my 3 month mark.
Ya registery is not that easy or quick and it's NOT a one trip thing. We picked BBB and Target. At BBB we didn't finish because I wasn't sure about a couple of things or measurements. At Target, we went through 3 guns before we gave up and said I'll finish online. But looking online is VERY overwhelming so I now have to find time, again, to go back and finish.
So now it's a little less than 3 months before our wedding and with 2 jobs, spending time with FI, friends, and family, cleaning the house AND taking care of the rest of the wedding stuff I have to finish registry. Ya...wish I would have done it a couple months ago when I didn't have as much going on.
So I suggest doing your registry 4-6 months in advance (like everybody else says) for the mere fact that it will get in the way if other wedding stuff.
