I have used this method with success.
Go to a silk flower shop or craft shop and get leaf ,fern or what ever type of vegetation type you like ,the ones with a flat style work best.
1/put abase coat of the color you want your vegetation to be.ie if you want a greenish fern.spray a base a little larger than your pattern, allow to dry,then take your leaf or whatever and hold it against the stock where you painted and spray over it with brown ,black ,oliver ,or whatever color you want.DON'T MOVE THE PATTERN WHILE SPAYING,just a light spay over the pattern is all you need . Practise on a piece of card board before you try on your stock.The only thing limiting you is your imagination .
good luck, chris
