We're making ours too, as we're on a low budget. Luckily they're things you can make while watching TV, and if you're ogranised, you can print them off a month or so in advance, so you're not in a rush. Alternatively, you can ask your bridesmaids to come over for a girly night, and make them together. They don't need to look cheap, and the good thing is you can make them to your taste without worrying about the high prices of the printing.
Here's our plans:
* We're buying A6 (A5 folded in half) card from a local stationer. They sell matching envelopes in a variety of colours. We haven't chosen a colour yet, but either black, cream or red (our colourscheme).
* We have typed our text, using the font 'Monotype Corsiva'. We're intending to print them and cut to size, gluing only the spine of the paper to the inside spine of the card, so it looks like the professional style of inlay.
* I have a friend who is both a photographer and artist. She is taking a photograph of us for the front, and then she will sketch it. We will then scan it and print them off.
* We will mount the sketch on borders, before sticking to the front of the card.
* Our RSVPs will be sent inside the invitations, and these will be very similar.
* We are buying wax too, to make wax seal effects on the envelopes. I watched a wedding show where they made the seal stamps from potatos, carving out your initials or a heart or something with a knife. Very cheap, and effective. You can buy the wax for the seal from www.confetti.com
I hope this helped. Good luck!
