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!
Always send handwritten notes. Regardless how brief, a handwritten note (as opposed to a preprinted one) illustrates sincerity and your appreciation for the gift.
There are many different ways and reasons one would sent a thank you card. Most people would think that thank you cards are only sent for wedding gifts and so on. But you could send thank you cards for birthdays, graduation,weddings, engagement parties etc. There is no limit to sending out thank you cards to people that came for something at your house or where ever.
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.
There are so many styles and designs to choose from. You can have piano shaped or topiary shaped or whatever shape you want, it really all depends on your theme and your taste. Just remember, creative and well thought out place card holders will add the perfect finishing touch to your big day, and they will delight your guests so much that they’ll definitely hold on to them even long after your wedding.
