Haha! You certainly are observant, Suz. Yes, you are right. I press each block when I have it done. And, I spritz it with a bit of best press as well. I want it to hold its crisp appearance until I'm ready to start putting these together. And, I've found that the inktense pencil colors will set better with a good pressing as well.
I'm almost done with block #20. I'll post a picture soon.
