I am thinking of purchasing some of these....
Grass Fields (different colours are available)
Leafy crops / vineyards
They are all approx 120mm x 100mm and cost around £6 each, not exactly cheap but you get what you pay for as usual
I like all these and they will definitely enhance my collection further.
The moorland clumps will be used to create some bog land pieces which after seeing how Ian created his water with the tissue paper/liquitex method has inspired me to look at creating some dark and gloomy moorland pieces using these clumps as islands in the water.
