These were all boxes I purchsed from Target and Michaels. They all work very well together! I have my Simply Renee Clip it Up in the far left corner and it has just enough room to swirl around. On display on top is my Project 365 album (Creating Keepsakes KOTM - January). I recently discovered how great the Cropper Hopper vertical paper holders fit into the 4-shelf boxes turned on their sides. I had the Croppers sitting up on their own but sometimes they would topple over (domino effect! - disastrous!) so that's not going to happen anymore. Right now most of the drawers on the far right are empty -- room for growth!
