Yo Yo Quilt

Aunt Cathy bought me a yo yo quilt at an auction she went to. Looks like it would fit nicely on a full size bed. It is a very old quilt. It really needs to be handled delicately.  Every time I move it, it seems I hear a tear or rip.  There are a few spots I need to fix.

I need some advice on how to clean this without it falling apart. The smell isn't bad, so I know it will be easy to clean up.  I just need advice on what is the best way to do this.  The only thing I can think of is when it finally gets warm out to soak it in the bathtub then hang it outside to dry.

Please leave advice in the comments section. I know there are many experienced quilters out there who can help me with this.

I tried to get a picture of it on a bed.

I found this interesting. One end of the quilt is angled on each side.  I think it is supposed to be finished that way because each side is the same.  However, what end of the bed does the angled end go on.  Should I put the angles at the top of the bed with the pillows?  Or I wonder if they are supposed to go at the bottom and maybe the angles help the top lay nicely on the corners.
