Addressing outer envelopes...hand written or printed?

I printed my own labels 150 my computer is pretty decent.

I am printing each of mine. I had to type in all of the addresses anyway so I just printed them instead of using labels.

For the small RSVP envelopes, I am ordering blank 4bar white envelopes and I ordered (and received) a custom address stamp. I will be stamping our address on the front of the white RSVP envelope for a custom look. I don't think that size envelope can be printed, so my option was a sticker/label and I didn't care for that. I'm really happy with how the rubber stamp turned out!

I ran my envelopes through my printer so that it printed directly on them and it looked great! I didn't know how to do a mail merge and didn't understand it after reading 3 different tutorials on it so I just went to word, changed the page size to the size of my envelopes, centered the text and entered down a few lines, then typed each address. After that I put a page break and kept going. I know its the long way to do it, but since I didn't know how to do a mail merge it worked and looks beautiful! One bit of advice is if you use a printer and a slick envelope (glossy or metallic), if it smears, spray it lightly with hairspray right after it comes out of the printer and let it dry.

Oh and have a few extra envelopes to test print... I learned that I had to turn mine sideways to go through the printer.
