CNC Fiber Path with Curve Attractor

Hi Everyone,

If you look at the image below you'll see that the vase in plan is more or less a triangle. Ultimatey the goal is to lay hemp fiber into the CNC paths and then brush on a bioresin. I'm struggling with implementing three curve attractors on the edges that pull the CNC paths toward  them but along the initial surface geometry. I want the "CNC" curves to clump on the edges and dissipate in the middle of the triangles span. Please help! I really appreciate any help you guys can give me.

Thanks,

Hunter
