Using the Curve Tube Snap brush then Dynameshing it. I'm sure Fiber Mesh is better/easier to do but like Insert Sphere, Curve tube is so versatile once you get over the first hurdle. It's quite fiddly to start out with lol.
Same here, I didn't know I had to tap the surface to make a new stoke. It kept editing the same line and driving me mad lol. I good idea is using the "Split" options In the SubTool menu after you've made your new geometry so it'll be on a separate layer. Keeps everything tidy
