I must be honest, I dislike ready made tree armatures. Maybe they're suitable for wargaming but for making dioramas are very unrealistic. Presented technique is good, though.
agree with you Dalibor . I shared because of the technique, which is a good starting point and adaptable to personal improvement. For wargaming, it would suffice a shaped paper with "wood" written on it but it would be a pretty cold and boring battle
Cheap & expensive pre-made trees fill my needs. An old plastic Christmas tree has enough trees o it (by pulling off the ends of each branch) to provide several forests.
