I've been painting tips and gluing them onto the end of orangewood sticks. Then I have some simple white square ceramic things, I think they are originally planters, maybe about 4 inches square. I filled them with tumbled stones and stick the sticks down into the rocks. The effect is allmost like a fingernail plant
I have about 10-20 sticks in each planter.
I have a planter with "bridal" colors and nail art, one with neon colors and funky art, one with "featured" colors and art of the month (seasonal and whatnot), etc etc.
This way I can display the available art and show the polish colors as they will actually look on the nail. When people want to browse my polish collection they dont have to rummage through my bottles, they can simply pick up an orangewood stick and even hold the polished tip against their nail to see if they like the color against their skin tone.
Also, I can rearrange and "feature" colors that otherwise might not be noticed sitting in the bottle.
I place the "nail flower pots" around the reception area of the salon to catch the eye of people waiting. This helps bring the clients who are just there for a haircut over to my nail area out of curiosity a lot of times.
Just a thought, hth.
