I discover today and it is late...
1. Group Build runs from 00.01 Saturday 27th May 2017 to 24:00 Sunday 4th June 2017 (all times GMT).
Just one day remaining, so no model (gluing/drying/PSR/painting/drying) for me, but maybe a drawing.
2) Any subject, any scale - but must be a what if. Profiles and stories also eligible.
3) You may build, draw or write as many entries as you like (good luck!).
It seems confirmed: no just 3D models are concerned, a drawing is possible too. So I will, very soon...
