No no stop! oh my ribs...
Super fast wall building
Oasis, for those who like me are a stranger to all things gardening, is a trade mark name for wet floral foam which is used in flower arranging.
It has some interesting properties for model making. It is incredibly light in weight and is very easy to cut with a scalpel, In its raw form it's quite fragile and has an interesting property that if you crush it, it stays crushed. It takes acrylic car spray paint without dissolving.
You can easily slice it into bricks for making stonewalls in the same fashion as making them out of cork tile but a really fast way of making quite passable (in my world anyway) stone walling is as follows:
Slice the Oasis into wall sized lengths with a disposable 'snap off' craft knife blade. gently round off the top of the wall by squeezing the material twixt finger and thumb.
Using a slim sharp object of choice, such as a needle or toothpick, scribe out the pattern of stones, larger stones at the bottom. I have found it works best for me by making the scribe marks narrow but quite deep.
Once the stones are scribed, I gently go over the whole wall with a fairly soft brush, this opens up the courses between the stones and gives them more depth and adds a bit of texture to the face of the stones.
If you want to toughen the Oasis up, give it a good soak in a 50% PVA /water mix, be aware that Oasis is very absorbent.
A blow over with grey acrylic car primer gets it somewhere near a good base colour and also toughens up the surface a little. Don't worry about not getting paint into all the cracks and crevices, the darker colour of the Oasis gives them depth. I use Halfords grey acrylic primer as it's good quality and the spray nozzle on the can gives good control over the spray pattern and delivery.
Once the base coat is dry you can set about tickling in various shades of suitable stone colours on individual rocks, adding little bits of green and orange to represent lichens and moss. You may want to add some highlights by dry brushing from one direction with a lighter colour. Subtlety is the key here. You can if you think it necessary, run in a little thin dark wash betwixt the stones, on the example below, I didn't bother.
The photography is quite cruel, but once in place on the layout and it blends in nicely.
One block of Oasis will make you around fifteen feet of stone wall in 7mm (O Gauge) about four times as much in 00. That's a lot of wall for around £3
