Landscape detailings

As i had mentioned i spent a few days just looking at the details in my previous projcts, in addition to this i had a look and tried to guess details for other peoples projects and sites, the aim of this was to build up a mental book of different things that work and dont..although i feel this is time well spent, i rather wish i had written all my findings in a book as i have just realised that remembering all these things without actually using and experimenting them will be rather difficult.
