I need some help identifying this piece.

Don't you just love vintage pieces?  I found this beautiful sheer floral cover a few months back but am just really not sure if it is a bed cover, canopy cover, or tablecloth??  I can see it used for any of these, but I would really like to know for sure.

It is quite large and will easily fit a twin size bed.  The floral detail is wonderful and the piece has a large ruffled border all the way around it.  I know it's not a duvet as there is no "pocket".  So I am hoping that someone will pick up my blog soon and let me know what they think!!

I'm thinking of putting up an old iron daybed and am thinking of using it...........what do you think?
