Any Ideas For A Deaf Theme Wedding?

I`m the bride (deaf) and my future husband is hearing (learned sign language from me). I am evidently not very creative or crafty. I`m stumped. I`ve come up with these ideas below but would like to ask those out there if they have any additional ideas to decorate our white rose/light purple flowers and deaf theme wedding.
1. I plan to order an ice sculpture with the hand sign "I love you" for our buffet table.
2. I have found champagne flute charms of the "I love you hand sign" to attach to bottom of flutes.
3. I plan to sign a favorite song to my future husband.
4. We plan to ask the guests to wave their napkins in the air instead of clinking glasses if they want us to kiss/or to get my attention.

Almost all of the guests are hearing, but they`ve expressed interest in my culture. A sign language book would be too expensive as favors. I would like to find some crafts or other decorations/favors with the "I love you hand sign" or other deaf theme ideas but I do not have a creative imagination. Any suggestions are greatly appreciated! Thanks!
