Here is a cheaper way to make large quantity of miniature trees compared to purchasing those ready-made miniature trees you will find in hobby shops.The materials you need are simple and easy to obtain.A can of glue spray(you can also white glue but it dries slower),a hand drill with a 0.5-1mm drill tip,some small branches that you can find on the road side,and woodland scenics' bushes.
When you are dealing with the branches make sure that it is completely dried,if not dry it under the sun for a few days.
If your branches does not have enough branches branching out,you can drill a small hole on the trunk and stick another branch in it,using superglue.This is important because if the tree does not have enough branches,the "bushes" would not have space to stick.
Now,you can spray glue on the branches leaving the bottom of the trunk clean.(Be sure to spray a thick coat of glue)
Dip the tree into a bowl of "bushes",and bury it under.
After taking it out,apply a little pressure on the bushes to make sure it is stick well.You can also trim your tree by removing or adding more bushes using white glue or super glue.(Do not use the spray on bushes)
Here is the final product,hope you guys like it.
Using bushes as the leaves let you create how a tree look when you are looking from afar.So for gundam because of its scale,i think it is better to use bushes.
For this diorama,this kind of trees are perfect for making a forest feel.
This is still wip,more trees are need.Next post will be on how to make realistic mountain.Please stay tune.
