I need to create a filling boxes velvet. In a box will later be inserted into a jar. Do you have any patent how I can create something like this?

Unfortunately I can not deal with it. Could someone look at my file and help me to model to make it look more or less like the image? I would be very grateful. <— blender file

check into the cloth modifier. should be just a matter of setting it up and letting it drop. then applying the modifier.

Do you Could based on my file which provided show how to do it?

I can make an example, but I’m kind of busy at the moment, so I made a sketch for the time being. This SHOULD work perfectly, …I think.
