For the kitchen scene, I used  large box. I cut out a window shape and added floral paper to the ‘walls’ to represent wallpaper. I then painted this with brown watered down paint to look like the paper was aging and damaged.
For the kitchen surface I used lolly pop sticks and match sticks and superglue, then painted these with dark browns and purple colours.  I also managed to find some wooden slabs in hobbycraft that I used for the floor.

for the detailing such as the cigarette butts, plate and bottle, I baked polymer clay and painted it with acrylic paint.

For the first idea of the ghost, I used polymer clay and created a wire and tinfoil ‘skeleton’ to hold the shape.

This didn’t work for multiple reasons. The clay was naturally a pink colour and had a very smooth texture therefore was difficult to paint. The paint did not stick well to the smooth surface, and it required multiple layers of white to get a full coverage and even so, there were very visible paint brush marks over the entire ghost.

Secondly, the only parts of the ghost that moved were the wire arms and legs, and I really wanted the ghost to look fluid and move around freely. The ghost was also very heavy due to the amount of clay, so there was no way to make it naturally float and look weightless.

For the water I used blue tissue paper, scrunched up. In every scene I moved this slightly so it appeared to be more fluid like water.
To create a ghost that was more flexible and manipulative,  I also used tissue paper, I started with a small bit and in every scene I added more shape. For the ghost to appear floating I added a small wire underneath and attached it to the ground with blue tac so it was able to move around. The wire was very flexible so could easily move the ghost to different areas.

I did this effect for the speech bubble also but with paper instead of tissue paper.
