My Invitations - Need Help on Final Cardstock Backing...new to partial DIY!

[AllieRay]

Hello BDW ladies, 

 

I have my invitations printed out now and I want to dress them up a bit!! Sorry about the rotation on the second one, I couldn't get it fixed. Take the poll and help me and the fiance decide! 

 Here is the invitation with the orange cardstock back. 

 

 Here is the invitation with no cardstock backing..so "as is"

 

 

Here is the invitation with the white cardstock backing (well as of now this is the envelope, I am just using it to get an idea because if I do nothing and go with the invite as is, then this "backing" that is actually the envelope will be what I send.  I do however, have a love bird stamp that I am going to put on the back of the envelopes.)

 

 

 

So if we go with the white cardstock, I'm going to buy the orange envelope. So here's an idea. 

 

Alright, what do you think? What should I go with? Thanks for all your help in advance!!
