And the bit I like. The main shift on the upswing to 7mm is the scenics. Ground foam won't do. I've not had the cash or incentive to enter into the sticky-up grass movement so beloved of the Model Rail/Hornby/BRM brigade (if I was a beginner today I'd be brow beaten into the static grass/airbrush/DCC/Photoshop model method which they all religiously promote) but being me I'll stick to the cheap bits of rubbish that I've always used. Here the rough grass low bank at the rear of M. Stanley has been covered in a mix of tea (builders and green) carpet underfelt and horse hair. Only the latter was directly paid for. This is pre-trimming and tidying with a pair of nail scissors.
