I did all my own save the dates, invites, RSVPs, information inserts, song request cards, order of the days and place cards so tha they matched as a range. We used ivory card & black lace as the design and I got some lovely prefolded hammel & decker cards with envelopes from Stationary Box and lots of lace & ribbon from a habidashery stall. The cards were also ideal covers for the order of the days and could be cut down to make place cards.
Also there is a website, something like 1001 fonts, where you can download loads of font set's for free and there are some gorgeous wedding ones (Ruritania was one of my favourites).
