Take a tip when using styrofoam for the very first time-Be afraid- very afraid
I can usually scratch build -in a fashion- most things for my dios but I had better results with fuzzy felt than I did when trying to build Alamo walls and buildings out of large chunks of that darn foam (and this is the guy who won a prize for his boy on Blue Peter for building him a Tracy Island out of old bog rolls and biscuit tins
)
I have stated on other threads that I doff my old gray kepi to the likes of Simon; Tim; Alex and others who have turned out magnificent foam structures but that skill is absolutely beyond me-my Alamo walls ended up looking like cat scratching posts.
Rob if you have that skill I'll willingly add you to my experts list but when you start carving for the first time-trust me- it aint easy and have plenty of black-sacks handy to throw all your rejects in
