I sent mine in 5 A4 sized envelopes. 1 for the sponsor, 1 for the applicant, 3 for proof of relationship. The envelopes are labeled 1 of 5, 2 of 5, and so on...with a description of the contents. I also put the courier address on a sticky label and stuck it to the back of each envelope. All 5 envelopes went in a plastic UPS express pack baggie...(I double bagged them just to be safe).
Inside envelopes 1 and 2 are the forms in plastic sleeves. Each plastic sleeve has a sticky label on the front describing the contents. The first page within the sleeve is the same label as on the front of the sleeve (printed on paper). I put everything in order according to the document checklists. There are no staples and no paperclips. Everything is loose (that's why I used the plastic sleeves...).
For the proof of relationship envelopes, again, I put everything in plastic sleeves as described above. I separated the envelopes into 1) cards, 2) photos (160 of them from 2006 to present), and supporting documents (travel stuff, letters from friends supporting our decision to move to Canada, hotel invoices / vouchers, samples of Gmail chat records from 2008-2010, samples of e-mails between my wife and my family in Canada, copies of my current and old passports, and a copy of my wife's old passport showing her visas for Thailand, our current rental contract for our apartment and our ID cards, and our health insurance policy showing my wife and son as my dependents).
We didn't go overboard, because we have been living together since 2006. No point in putting in a lot of e-mail stuff or other evidence...they won't expect this for our situation.
Anyways, it is all very easy to navigate and I'm sure the VO won't have any troubles...
