Initial adjustment:
Something that worked for me and turned to be a 99% solution. When I added the male inserts/clips I made sure the clip was fully seated in the opening pic 1. The corners are oriented on about a 45* angle. Pic 2 is good shot of the orientation.
Then, starting with bottom of the card, I inserted the clips from corner to corner. I tried initially starting on the top corner to corner. Soon realized I couldn’t see the bottom (duh)

of the card. Regrouped and adjusted fire. Starting from the bottom going corner to corner made it easy/simple.
