Progress on the solid squares

I have 7 pale blue solid squares made, and I've run out of the pale blue yarn. They're 6 inch squares, and my bed is queen sized (The mattress is 60in by 80in), so I have a helluva way to go.
Someone want to do the maths for me on how many more squares I need to do?

More squares!

I've done another solid granny square like the one I did on Friday night, and am working on another.
I'll get enough for a blanket... eventually...

A solid square

Todays square is a 15cm (6in) pale blue solid square, based on the pattern from the lovely Gingerbread Lady.
I likely will be making a lot of these in different colours. Or just the one.
I haven't yet decided exactly how this blanket will be constructed, but I have a feeling it will be alternating squares of plain and pattern, creating diagonals.

(And yes, that is the shadow of my hands and the camera)

And now, since it is gone 1am, it is bed time.
