diy canopy bed - so easy

As I kid I always dreamed of having a canopy bed.  I am super lucky because I happened to marry the son of a furniture maker and got the bed of my dreams as a wedding present.  My daughter, however, will have to wait a while before we can afford/have room for a bed like that in her room.  However, this idea might change all that.  It's basically the easiest idea ever.  In the picture it does look like they have some fancy way of drawing the curtain up, but I don't think that would really be necessary.  Just a simple drape would work...Hmmm.  I'll have to keep my eye out for some thrifty fabric that would suit this purpose.
