The main difference in the two cards is that the Wonderfolds have a elevated floor panel inside the hexagonal box with slits cut into it. The design elements of the card (bridge, tree, girl) are attached to tabs which are threaded through these slits and anchored inside to the bottom of the box. After a little bit of fiddling and playing around, I added an extra panel to the original Hexagonal Pop Up Card template and to come up with this card.
I've been leaving the backside on the Hexagon Pop Up cards I've made in the past rather plain, only adding my greeting or sentiment to the center panel, but this time I felt compelled to decorate the backside as well. I added a paper pieced bamboo and panda to try to give the card a 360 degree view, just like the Hallmark Wonderfold cards.
Ahhh! And for me the coolest thing about this card is how it easily folds flat when the two side corners of the box are gently squeezed. Yay! New fun card style to play with!
