Painting and masking?

[pumpsnail.livejournal.com]

Hi everyone!

I'm trying to paint a bunch of chopsticks to make hair ornament thingies, and I got the idea that if I used masking tape on parts of the sticks, I could paint more accurate stripes and things (as opposed to just trying to paint stripes evenly by hand). Well, on the ones I've made so far, some of the second color of paint (I painted the chopsticks a light color using acrylics, waited for them to dry, put on tape, and painted a darker color over it) leaked through the tape and so the stripes look kinda....icky. Is there something I can do to make this not happen? Possibly some other type of masking solution (I bet rubber cement would work really well, assuming it doesn't peel the first color of paint off)?

Thanks!
