How to model a flattened inflatable object?

Hello,
I am new to Sketchup. I can only manage to do some simple solid stuff. But now I have to draw a flattened inflatable object, like the one in the photos. It has some bubbles inside, so it looks more like fabric with crease ( I don’t know how to to that either, too advanced for me)

Can anyone give me some ideas, please? Just general steps will help. Thanks!


Using Quads and Clothworks extension

or try modeling in Blender and export as OBJ or DAE files, then import in SketchUp

The complexity depends on what you want to get in the end and how you will use the model.
