"Can you tell me please, did you wet the backing on the mounting board before peeling it off the foam?"
No I just picked up a corner and peeled it off.
"How did you do the brickwork? pencil & ruler?"
Yes ruler and pencil.
Thanks again for all the kind comments. It was a fun project and one that was long overdue. Hopefully once we can start gaming together again I will run a Dark Ages campaign based in the time of the 1st crusade. Field battles will be fought using To the Strongest rules and sieges will use Tactica Medieval rules that have a nice set of siege rules. I will probably create my own campaign map and the campaign rules.
