Within the world of model railroading it seems that “Modeling Trees: part One: Broadleaf Trees” by Gordon Gavett is the “Holy Grail” for those interested in such things. The book is unfortunately out of print. A review on Amazon.com states – “This has to be the most authorative book I’ve seen on the subject of scale modelling trees. The author takes you through the procedures for creating the scale model, the techniques, materials and tools. He then sets out a series of worked examples, for instance, silver birch, weeping willow, oak. While the book is aimed at railway modellers I don’t think it matters whether you are modelling dioramas for tanks, or building wargames terrain, if you want to create authentic looking trees then this book is the one to get. There are no easy methods though, as he explains in the book to get the right effect it takes practice and time. Some of the examples in there have taken 15 to 30 hours to do! But it is worth it – the end result is incredibly life like. He also touches on other things like creating ivy going up a tree, but I particularly like his bird nests! Would I recommend it – well I am just going to buy volume 2!!”
With the book out of print, the copies you CAN get seem to have been priced by their weight in precious metals. Amazon.com UK has a couple but the cheapest one is £19.99 – about $33 – and shipping hasn’t even been considered yet. Darn it.
