If you want to destroy my sweater...er...scarf

So my DS asked me a few weeks ago if I wanted a scarf of hers that had started to unravel.  Being the yarn hoarder that I am, I immediately said yes and then forgot about it.  A week later, I received a package with a scarf in it:

So below you will see the process of me unraveling this very long scarf.  It was crocheted and each row is a separate piece of double-stranded yarn.

Fortunately, this scarf was very easy to disassemble

 

An Old Navy scarf, and they didn't even knot the yarns together, just finished one row and started another.

 

All the yarn except for some short fringe

 

Now I just have to figure out what I want to do with this yarn as it will require lots of joining.  I was thinking some hand-warmers, a cowl, and a hat if I have enough left over...and then I'll sent it back to my DS!
