I saw this fun card fold on a YouTube tutorial by Rachel Tessman. She called it a tucked Z fold.

I have used Playing with Patterns DSP and the Zany Zebras stamp set for my card. The card base is an A5 Bermuda Bay folded in half .I used the largest layering circle die to cut the hole in the front. The folded piece inside is 20cm x 14.4 cm and is scored in landscape position at 10 cm and 15cm.
