This set is 3 laser-cut (and scored) pieces of medium-weight chipboard. There's an outer cover that wraps around so it has a flap on the front when closed.
Then there are 2 pieces to be attached to the back as fold-outs: 1 to extend up (when opened out fully) and the other to extend down. So it's like a big plus sign when fully open.
The scores will make the narrowest fold-out have room for 1/2" depth, then the second fold-out has 3/4" depth, and the spine on the wrap-around cover is 1".
Lots of space for add embellishments or more pockets.
Note: there's also a smaller version of this folio linked below (4.5 x 5.5 Inch Mini Folio).190627new 190627G GND
