Always send handwritten notes. Regardless how brief, a handwritten note (as opposed to a preprinted one) illustrates sincerity and your appreciation for the gift.
The very first thing that you need to have in preparing your invitation cards for your wedding anniversary is a set of computer to be use for encoding the names of guest. This is also the same machine that you need in designing your invitation cards. You can personalize your card depends on your motif, and then accessorize it like adding ribbons, beads, and photos.
Don’t procrastinate! Formal etiquette dictates that thank-yous for shower gifts should be sent within ten days and those for wedding gifts should be sent within two weeks after returning from the honeymoon. Moreover, gifts received prior to the wedding should be acknowledged immediately. That being said, if you happen to fall behind, rest assured it is never too late to be gracious!
Invitation cards differ from the type of celebration, to be conducted and in this case, having an invitation card for your anniversary simply focuses on the number of years you are celebrating your wedding. You can create invitation cards for silver anniversary, golden anniversary and any other anniversary.
You could also consider using a greeting card software. Purchasing the software is going to be cheaper than having the invitations professionally printed. You can also reuse this software for several other occasions. There are some Microsoft Office product like Microsoft Word and Publisher that would also work great for you to create your own engagement party invitations. They have already made designs and the Microsoft clip art can add visual enhancements to your engagement invites.
