I have made a couple of different mask patterns, and I find that the pleat structures really make a difference in how they feel over your face!

I totally feel you about the glasses and mask problem - I had to switch to a different pair to get a fit that would stay on my face while wearing a mask. I found a tutorial that suggests cleaning your glasses with soap and water helps prevent fogging, as does putting the mask on and then putting your glasses on OVER the mask. It's not perfect.
