I got the first large set for Christmas in 2010. The only thing I have to say is be careful if you re-create these. We ended up cutting them in half to get them into my new apartment!
The top shelf holds 2 shoe boxes/photo boxes on top of each other. The bottom shelf I made 13inches tall to hold all my 12x12 page and class kits I knew I had. (I need to actually do some of these! LOL) the shelf above that holds the cropper hopper paper holders perfectly. I made my cricut at a height I thought would be good for cutting and it is perfect. We added the drawer when I upgraded to the large cricut so I could pull it out some. The mat was hitting the back wall. There is a hole behind the cricut for the cord. The rest of the shelves ended up being a default size and we added some dividers to help portion the weight out. I still need to paint it though. It will either be white or yellow. I am still on the fence.
