Here we have video game characters, Kanye, and cartoons inviting people to Ian and Maureen's wedding. Maureen Alarid of the Offbeat Bride created this invitation featuring Admiral Ackbar's marriage advice.
At-home cards aren't a necessity, but if you want to let your guests know where and how to address you and your partner post wedding you may want to consider adding on at-home cards into your invitation package; or save it for after the wedding to send out.
The world isn't perfect and neither are your parents. When it comes to high ranking, divorced, or widowed parents, the situation could get emotional, frustrating, stressful and you'll have to control your parents' jealous feud over whose name (and who should pay for your wedding) should be mentioned in the invitation.
