These cards especially come in handy if you are planning a wedding in June, September or around the holidays, since they are traditionally busy times of the year. A save the date card should be sent out as early as possible. This allows your guests to avoid making plans for that day. Many invitations come with a specific save the date card that coordinates when the celebration will take place. Choosing coordinated save the date cards and invitations means making a decision early on about which design you are going to use. It also adds a nice level of customizations to your invitations.
Make sure to not crowd the card by only listing top priority points on the wedding invitation. These points include the time, place, hosts, names of the bride and groom, and RSVP details. If you want, you can also include the dress code for the ceremony, but you do not have to. When you try to put too much information on the invitation, it can get hard to read and look chaotic. Make sure to never list gift registry information on your wedding invitations. This bit of info should only ever be listed on your wedding website. It is not respectable to put these sort of details on your invites under any circumstance.
