Most suited for OO, HO, N and Z gauge. Seafoam is a natural product which can be ''planted'' straight from the box if you wish, but a little extra work with scatter material is well worth the effort. Scatters for the foliage come in three forms- flock, foliage and leaves, in a range of greens and autumnal tints. All the modelling techniques needed to enhance this product further are fully explained in the instructions.
