Today I have been working on creating fir forests fir my 1/600 and 1/1000 games.
For my next Operation Sealion game I needed 39 hexagons of fir tree forest. I tried to make them in a way that they would appear to be continuous forest but would also accommodate either a 60mm x 5mm or a 15mm x 10mm base.
My 60mm bases are of MDF bought from Wabases.com. The trees come from Busch model railroad suppliers, from their N/Z range. Most of the trees are to large, so I used the smaller ones by snipping off the trunks anc cut the larger ones in two. The lower half was trimmed with scissors to copy the upper half as far as possible. A splash of dark green paint on the tip of the lower half disguised the cut.
Here is the process:
