I struggled with what I wanted to focus on, but then I had a sudden idea and decided to try making a desert diorama for the first time! ‼️
This was the motif that came to mind. lol
The key points I focused on were the sand and the base. Well, I'm "reusing" the plastic waste generated by my company, so I decided to enter this, even though it's a bit of a bizarre commitment. 😄
I'll admit it, I work for a plastic cutting company. lol
First, I used a scrap piece of a material called Ultem for the base. It's just the right thickness and size. For the sand, I used a type of ochre-colored wood called Sepra.
