Hello Folks, I found this old hinged case, so I stuck some chicken wire in both halves, and have laid down plaster wrap on the lower half. Just random wire with no thought of shape in mind. Just a flatish spot somewhere.

The top half, Im not sure to make a 3d background or another diorama that is flat.

I kinda like the idea of a 3d background, I think the box cost me 30 bucks a few years ago, same as building one but Im lazy. So I could have this snap open full 3d diorama and swap models you see kinda sorta.

I will dust it with black tomorrow so you can see the landscape, Ive ended up with a nice Wadi effect I think and the scale seems to be good too.

Plaster bandage is drying and a coat of plaster mix mit pvc glue will go on in a few days.

1/24 and 1/35 models

I couldnt helop myslef, I gave it a quick spray to see if I got a sand dune effect ish type of wind blown thing, looking good as just the base, I think I fluked it. Cant beat chook wire for cheap projects.

I poured some plaster on mixed with PVA glue after I wet the base. Poured on some fine granitic sand gave it a bit of a rub to reveal high spots, will let it dry and then give it a brush and see what we have.

Ive stalled for want of alcohol.....to wet the sand with.

Having troouble finding the Isopropyl in bottles, can I use metho to wet sand before applying the watered down white glue I wonder?

No clue about your alcohol and sand question there, but putting your dio inside this box is quite awesome, looking good so far.
