If you are creative and want to save money, you can create your own save the date cards using either card stock paper or regular paper. This will save you money since you will be printing them yourself. You can be real creative when you design these. You can include a picture on the paper and include any other personal details you would like.
Stop to think for a moment: You have painstakingly put together your wedding event, and done all you could to make this as perfect as you wished; but you take a look around your guests and realized that only half of them were able to make it to your wedding. You obviously missed out your wedding save-the-date cards to ensure your guests kept themselves available on this special day of yours.
When you decide to include photos in your cards, it is advisable to use photos that were taken after your engagement. It could be about how your life has changed, or how the both of you have walked thus far.
You should send save-the-date cards to all of your intended guests when either of these circumstances fit your situation. Even friends and family members who you already know will attend should be sent a card.
Another well received way is to print a mini calendar page with a 3-hole punch so your friends can attach it to their own calendars. Of course, you would have to circle or decorate the day that belongs to you.
