You know all about wedding invitations. These are those nice little cards with the pretty pictures that tells everyone where and when they have to go. It should be simple, but nothing associated with planning a wedding is ever simple. There is going to be a lot of confusing over just which card is the right one for your occasion. I unfortunately can't do a whole lot to help with the design. You'll have to pick something that matches your theme. I can give a few good tips though.
You don't want to make the whole process too complex. Just get some nice Carlson Craft wedding invitations from an online dealer or a local broker. Carlson Craft is well known for providing simple elegance when it comes to your invitations. There are plenty of other options, but they may not offer as good of a deal for bulk purchases. You shouldn't have to spend too much on the cards, but it is worth it to have a nice design in place.
The most important thing is to make sure that the cards are properly printed. You don't want to make a few hundred phone calls correcting the card later on. Just take the minute to check the time and place before it goes out to the printer. Also look at the design and make sure that your message isn't buried in the pretty colors. You still want people to know what's going on. Pretty wedding invitation cards don't mean much if nowhere can tell what you're trying to say. In the end, they are just cards.
Other than that, there isn't much else to say. Just take a minute and buy a basic set of cards that look nice and get back to planning the really important aspects. It isn't something that is worth much worry. A nice design with the right information is all that you really need to have a good wedding with friends. Anything else is just icing on the cake.
