need advice on modelling strategy/tools to use


Hi, I am fairly new to Evolve and so far I think it is a fantastic software. Looking forward for the 2018 version that I have seen will be easier to use. I am currently doing a practice model: a dish washing brush. I need some tips/suggestions as to what modelling strategies/tools could you recommend me to use to model this product? Please see attached pic with my specific questions in the image file. The 1st image shows the model I made using freeform/sculpting polybnurbs strategy. I choose to use this modelling approach instead of surfacing techniques like loft and sweeps as with the latter I had less control to get the shape of the brush . I would appreciate if you could give me some suggestions in regards to my questions I asked in the 2nd image.
Thank you,
Mark

Once you trim to get the blue part, use surface offset with thickness enabled. Extrusion will not follow surface normals precisely.
