Rubber band Animation

CurtainPicture , rubber band Picture

Hello All,
I have a cutain and a rubber band…I want to animate them (sliding up and down for curtain and ring sliding for rubber band… how can I do(tools technic advices are welcome)?
I now this is not related to Unity but I think that I can best answer here.
Thank you.

As taters says, just do a “tank track” texture animation on rubber band. I would try to do a similar cheat (with half transparent texture) on curtain. If it had a single color than you could scale it on single axis and it would be sufficient.
