I posted pics on my scrapbook gallery, so you can see what I'm talking about, but I saw this layout, and want to try it, but not sure how. The layout opens out like a gate. Then, under that, there are four squares that pull up and down. (2up, 2down). I'm trying to figure out how you secure these and still have them open. Any ideas? There were no visable attachments such as photo anchors or Brads. Any ideas will be greatly appreciated!
