Yes! I found localy some thick foil (0,5mm) for tents or roof window for cabriolets with soft roofs. I bought some to check in home. Thick but perfectly sewable and soft. Before this, I used more solid materials, like parts of packing, but this is much better.

Furniture foam - I made a cube out of it and after putting it inside (the hole was under small box) I filled it a little. Thick foam will better hold the shape, but it will be harder to put inside.

I used 10mm EVA foam, I cut a channel on full length, put a thick wire in it and I sank it in hot glue and make it smooth and flat. Inside of plush there are big elements out of furniture foam, with wire glued between layers. And there are two connection points, so it stable and don't fold.

Right now I have closed commissions, but when I will be open, I can make new one for you. Chceck the link in my bio for more info about commissions. If you have more questions, just write a message
