random dots on lures?

[crankybait]

well hey guys. you might know that i took up luremaking and havent posted anything new for a while. well, im pretty much out of materials, so tomorrow i go buy some new stuff. or amybe i wait for a sale on sunday. anyways,ive been thinking of new color combos, like mixing metallic with nonmetallic, new crazy combos and stuff like that. while browsing around lrues to get ideas from, i noticed some lures have random black dots on them. just one dot. i only see one side, so is the dot on only one side or both? and does this have any purpose? which also brings me to, how do i do small details? my airbrush covers a wide range, and i cant focus it to the size id need to make like stripes or the lttle things on firetiger lures. ive been thinking of making paper stencils, to cover the lure with while i airbrush small things. any comments on anything i just wrote? thanks
