See how the ribbon handle pops up through the top? The cover is about a 7" square and it is about 12 1/2" inches tall, so it isn't really big. It just slides down over the top of the unit. I made it this way so it wouldn't have to be made super sturdy to hold the weight of the unit.
Just an FYI for anyone wanting to make one, I used medium weight chipboard I purchased in the art department at Hobby Lobby and when I mod podged the paper to the outside it made the sides bough and that drove me nuts so I took some heavy chipboard 6" squares I had and used Aileen's Turbo Tack glue and put then on the inside and now the walls are a perfect square! Well as close to perfect as I could get :)
Here is the cover and the storage unit side-by-side. I love it! Now I am afraid I am going to feel the need to fill all the slots with distressed inks! Lol!
Please let me know if you need any tips or advice on making one. I would be glad to help but just a reminder that I used the wonderful pattern from this blog - Jen's Joint. She has very generously provided PDF's you can print with the instructions, pictures and labels for your ink pads. If you make one be sure to tell her thanks!
