RP 09 board- printing your own invitations

Does any one plan on making their own invitations? FH and I went to party city today and we saw the invitations that you print yourself. It doesn't look that hard and it will save a ton of money. Has anyone done this and is it as easy as it looks?

I have used the print your own ivites from Michaels and they were fairly easy, if you know how to work you computer and printer. Most of the print your own invites are a bit thick and need the thick paper/envelope option on

But there are plenty of girls here who have used them.
