Insert Mesh - Can't place multiple curves?

[system]

I am trying to create the fiber railing on a tactical vest, such as in the image below:

When I use the insert mesh tool, and drag it out, it works just fine. I am going to need like ten of these on multiple sides of the object, and I dont think sculpting it directly onto the mesh will be a good idea. Is there a way or a hotkey to place multiple of these curves on the mesh?

I have a second question: Is there a brush or method to make a uniform consistency to a mesh? Sometimes when I use Dynamesh I seem to mess something up and the mesh breaks because its too thin, and recomputes poorly. If I can have an equal depth to the mesh I think that would fix it once I get about what I need.

For multiple curves you could either click on the mesh to accept the result and turn it into a model before drawing a new curve. Alternatively you could switch to a brush such as ZRemesherGuides and use that to draw out several curves before switch to the IMMbrush.
