thanks for all your comments and encouragement guys

I reached about 70% completion with the lentils last night after spending a good couple of hours solid on it.  I was quite pleased to find that my lines were true and accurate and lined through with the direction of the kerb stones! 

Not much left to do now then I can concentrate on the little "twist" in this tale!  Then a whole load of painting and construction work on the building.

cheers
