So I've done some thinking. We are offering guests the option to make a donation to BARCS (in lieu of gifts) in Duke, Corrado, and Harley's names. Because each of them are rescued pets. You can view our charity wedding registry here.
My venue also has a large screen in the area where cocktail hour is. They told me I can put together a slideshow of pictures and they will play it on the screen for my guests to view as they enjoy some hor d'oeuvres and drinks. Then a light went off in my head! In the middle of pictures of Jon and I, I am going to throw in some pictures of my boys.
For those of you in the wedding planning process, I highly recommend asking your venue if you can display some photos in a slideshow fashion. It is the PERFECT way to incorporate your pets in your wedding :)
