Not sure if you've figured this out already but - I do nail art, so. Make sure you're using filtered or distilled water, and it needs to be at room temperature, water that's too cold or hot will set your polish too fast. Also drip the polish with the brush almost touching the surface of the water - it should be able to run off the brush and onto the water without actually making a seperate drip. Not sure if this is helpful or not... Good luck! You have some great colour combos going on there.
Thanks. I have had problems with it drying on top of the water too fast, and I think that was because it was too cold, and I was not using filtered water. But I will fix those two things today and try again.
Also I am having a lot of problems with making the straight lines in some of the pictures seen here.
http://geekhack.org/index.php?action=dlattach;topic=64752.0;attach=80864;imageThe nail polish will either be too clumpy or be too thin and be transparent, almost mixing with the polish next to it, creating mixed colors instead of the interesting straight lines that are desired. And I am also having trouble removing the excess paint on the top of the water quick enough. Currently I am having another person stand near me with two Q-Tips and having them remove the excess as quickly as possible after the cap is dipped (top down) into the paint. But commonly some of the excess will fall back down onto the key, therefore ruining the design, making it bumpy etc. Or sometimes the paint will be far too thick, making it uneven and blended instead of having straight lines.
If you can help me address any of these problems I would be very thankful. I'd love to make keys as cool and as sharp as those in the picture.
