I get really intimidated by having a huge card that I feel I need to fill with writing! I end up trying to fill the space up and completely waffling on.
So I started making tiny little cards. They are SO cute and people love them. It completely takes the stress out of writing on cards too!
Taking this on a level, if you're planning a wedding, why not think of making little packs of miniature cards and envelopes to give your guests as wedding favours. You can coordinate the cards to your colour theme, tie them up with string or ribbon and add a tag with the guests name.
For as little as £1.00 (or even less), you can create a pack of 5 beautiful cards. If you want to push the boat out a little, you could add a small embellishment to the top card.
Your guests will love such a thoughtful wedding favour!
