You're right. I only did very quick calculations. I can probably drop one block in width and one in length. That would give me a dimension of 78x93, with a total of 35 blocks.
The bed from floor to top of mattress is 25 inches, and I purchased the thinner mattress. I'm over 6 foot tall, so I don't have a problem climbing in and out of the bed. The quilt should just come just below the bed platform. And I like to cover my pillows with the bed spreads, or in this case, the quilt
I am wondering just how anyone can maneuver a king sized quilt through a machine. I would imagine that lots of the finishing stitching would have to be done by hand.
