When applying grass fibres with a static grass applicator they often lay perpendicular to the surface. And on slopes, this means the fibres can end up lying sideways rather than upwards as they would do naturally.
Lars-Christian Uhlig, a modeller behind the stunning Walburg project explains his technique to overcome this problem and a few tips to improve the look of your static grass even further.
To start with, a basic greening from mainly short fibres is laid. He uses a length of predominantly 2mm but interspersed with fibres with a length of 1 and 4.5 mm to vary the look.
To this, PVA is dabbed around using a size 1 or 0 brush. Slopes tend to be dry and rarely mown so a mix of beige and brown fibres with a length of up to 6 mm is then placed into these glue spots.
[Walburg is an HO layout so you might want to use shorter lengths if working in N scale, I use 1mm for starting fibres and 2mm for longer grasses on my N gauge layouts — Andy].
Once this is done, the fibres are then gently nudged upwards using the rounded tip of a camera lens cleaning sucker while a vacuum cleaner is held just above them, both acting to angle the fibres upright.
(For the removal of excess grass, Lars holds a small vacuum cleaner held just above and puffs with a camera lens sucker to dislodge rogue strands so they can be sucked up. Rather than losing and wasting material, a stocking is pulled over the vacuum nozzle so the excess can be recovered and used elsewhere).
A video of his technique is shown below.
Finally, Lars has noticed that the flowers and panicles often grow at the top of long grasses (think of oats) so he uses a wide soft brush to apply a gentle coating of glue and then sprinkles a very fine scatter or flock over them. This is shown in the video below.
The end results are some of the best model railway grass I’ve seen. From the variety of length to the flowers at the top of longer grass stems to the drier grass on slopes compared to the richer green in the meadows behind it looks stunning.
