All I did to make the path grey stone was use a dry paint brush and dip it into grey paint (painting it first onto a paper towel to remove excess)and then brushing over the stones. Try not to get paint in between the stones. If you find you are painting on too much paint use the paper towel and gently rub some off. I used two different greys to give some high lights and low lights. Once dried I used some reindeer moss( used in florist displays) and some flocking( used in Model train scenery) to add some mosses and lichens.
Black painted path and road
Now dry painted with grey paint.
Path now looks like stone.
With added moss/lichen.
Adding pva glue between the stones to add more moss/lichen details. I also used some reindeer moss to create a little hedge.
Well I hope you enjoyed part four I shall post up part five soon. In part five I will be adding more details in the garden.
