Thank you for your answers.

I havent found black nylon here in Singapore (at the moment). So I have tried with "standard" sewing first. (Too many thick fingers).
Waiting for my mini drill (0.5mm) to create some "rat lines"
And I have changed/added some paintings (using Citadel shade "Seraphim Sepia" for the sails and normal CITADEL colors for masts and square riggs)
Many plans in my head for building addons (like smoke markers).
We will see....... :-)
