Can we do this in Unity 3d?

Hello Every One,

This is the really tough to do for me. Actually i have tried to do below concept obviously i knew i cant do with out any idea. My concept is interactive simulation work for stitching two objects using thread and needle with any animation can we do this in unity 3d using script and other function?.

The concept is there is two object(cubes or something) in the scene. I have one needle i take that needle and tie one thread then using this i prick the first cube now the needle should go inside the cube and also thread then prick the another cube then i tie up this two cubes. After tied up this both cube will be stitch. This is my concept like doctor do the surgery. Hope you will understood. Help me to do this.
