Well Bailey, I'm an in the box kind of thinker. So it's hard for me to give ideas to someone who is not. With that being said, Do you have a daughter who may want to wear it on one of her other fingers? Or a grand daughter?
It could be used as part of a knocker for a door, a tire on a vehicle, as a ring on a necklace (you know how pregnant women sometimes can't 'fit' into their pre-baby jewelry when very pregnant), how about having it be on a finger of a newly wed (you know those hand over hand pictures when couples first get married), use it as the frame of a mirror, sewn to a pillow (think same wedding reference), or how about using it as a bowl and filling it with _______(porridge, gold fluff, fruit....).
Phew! That was hard for me. Do you see the sweat beading on my brow?
