Full/Queen question

ArcticFox

Hope this question even makes sense - do most sheets/blankets come in a full/queen size, or can you buy either (just full, or just queen).  I guess I am wondering what the difference is?

The reason I'm asking is because I had bought a bunch of stuff to fit my DD's full bed, but I'm wondering if it will fit on her sister's queen size bed (like Dora sheets, now that DD has outgrown Dora).  I have to go dig it out and try it on a laundry day, so I thought I'd see if you guys know off hand.
