I am sure you can identify with rummaging through your apartment looking for a safety pin or some odd object to stand in for the real thing. A few weeks ago I needed a small bud vase for a clipping of a spider orchid and was shocked to find NOTHING that would do the trick. The stem was fat and the clipping was short - neither of my vases or any odd jars or cups would work. But I did find a cute solution in my fridge...
Remembering that eggs can make great seedling starters, I realized that the omelette I planned to make could also yield a good little vase. I used a chopstick to tap the top and then to siphon out the inside. I had a little soy sauce dish that I felled with sunflower seeds (salt or legumes would probably also been fine) and it was perfect to hold the egg upright.
I would love to try this again, and can imagine nicer, more permanent and elegant solutions. A Martha Stewart website article showed how ostrich eggs can be used in the same way.
And as a side note, the spider orchids were great, but did not last long. They were gone within a few short days, having shriveled up so quickly in our hot, dry apartment. But here is a picture of them in their pre-mummified glory:
