Could be a nice touch when you have guests visiting...

Nope. Wet hands reach over to grab a leaf, dripping water on the lovely arrangement. About 3 handwashings into your party or guest's stay or whatever, you've got a fused mass of soap in a dish.

It's a guest soap that skips the gross "used" look in favor of actually being used up!

Eep. Cmcinnyc is right.

Back to pump soap for me.

Cmcinnyc has it - that's actually what happens - my mom has tried these.

Maybe these can be affixed individually to a twig/branch. That should help to keep them from fusing... I think.

I have a thin little cardboard 'wallet' of rectangular soap leaves that weighs nothing and is just great to carry around in my bag - if I remember. Very handy when you're in that city bathroom with no soap (like the one at Union Square, near the farmer's market and the outdoor park cafe). Or at gas stations across the country. Of course, I take my little leaf of soap out while my hands are still dry, and it works like a charm. I forget where I got it, but it was pretty cheap.

I'm thinking perhaps an origami of some kind that could hold the leaves for easy "plucking" would be handy AND lovely.

oh, pluckable origami soaps are a great idea, then the not-so-forward-thinking who grab the soap after wetting their hands won't mess all.
i too have the portable soap leaves!
