would love some ideas of what to have our guests hold/wave/do as we exit. we're getting married on a boat so as we are disembarking we cannot have bubbles (makes the ramp slippery), birdseed/confetti/rice (because of the birds & fish), and i've read that sparklers can burn your dress if someone gets too close & i'm not 100% on how much room we'll have with everyone standing around.
any ideas/advice would be wonderful!

TIA
