I seen these the other day on Etsy:
Seashell Hair Combs for the Beach Bride by beachgrasscottage
White Bridal Flower with Seashell Accent Hair Clip by WeeGardens
Hope this helps!
Yeah I like the maraca idea, maybe tie the wedding charms to the maracas. If u are a bride on a budget, check out oriental trading:
Painted Maracas
Definately put them on the table rather than in the OOT bags!
