Next time you're cutting patches for a project, don't stack them exactly on top of each other (left) after you cut them. Offset them instead (right) so you can tell how many you cut without flipping through the entire stack and counting one by one.
I cut these blue patches 4 layers at a time. I can tell at a glance that I have 8 cuts of 4. So, 8 x 4 is STILL NOT ENOUGH!
