OK - Project Sheep is in progress. Materials acquired. Board and box sorted. Design complete. Timings planned. Risks identified. Tolerances specified - contingencies planned. Transit arranged. (Yey for my PRINCE2 qualification! - more useful outside than inside the office

)
I am doing a 3 layer tall madeira that I'll carve into a rounded edged sheep-like body, covered in a marbled (ivory and white) sugarpaste to give the approximation of a woolly coat. Legs from two mini swiss rolls covered in a darker shade of ivory (sheep always have dirty legs!) For wool I'm going to do some pronounced swirls atop the base layer, because hubby can help with those and it's not too tricky for him. I'm undecided whether to do a shallow small madeira to shape into an oval-ish face, or just use a moulded lump of sugarpaste. Am inclined to the former even though it's more work - any views?
And to finish, I am toying with covering the (rectangular) board with some grass-green sugarpaste with some tufts (pushed through the extruder), and dotting some daisies around on it. Last covered board I did was of the Windows 7 default background - hand painted and shaded - it took longer than the WIndows logo cakes that sat on it...)
How does that sound? Any thoughts or suggestions?
And... never marbled a large quantity of sugarpaste before - any tips for not getting it too blended so there's still some marbliness to it?
