Quilt blocks

The quilt top is all sewn into big squares. Now I have to sew the big squares to each other. The pressing portion is really slowing me down, but I know it's necessary. What drives me crazy is that I still have to wash this quilt top, so after I wash it, I'm going to have to re-press all the squares. I'm bad at math, but I'm pretty sure there are 396 squares here and that's a lot of pressing.
