I put a top attached from the back but it kept popping up but when I turned it around and attached it from the front, VOILA! It worked.
The pattern is my basic rectangular popup box with the side and front panel cut off. The basic pattern is below.
Turn the panel so that the first panel you scored is on the right and the panel you cut out is in on the bottom.
Take the piece of 2 1/4 x 8 1/2 inch panel you cut out and cut a piece 2 1/4x 3 1/2 and score this along the 2 1/4 inch side at 1/2 inch - this is the table top and you need to attach this to the FRONT of the box - !?4 inch scoring made it a bit too big - 1/2 inch seem better but you may need to play with it to fit perfectly.
The top drawer piece was 3 1/4 inch long, the bottom three drawers were 2 1/4 inches and the little drawers on the right were only 3/4 inch wide. I cut little 1/8 inch strips of silver cardstock to mimic handles on the drawers.
The tools were diecut using Silver cardstock from Stampin up (retired)- and used a black sharpie to make the handles and mounted using thin slices of dimensionals. Some tools were lifted with dimensionals to give some depth and the signs can be changed to fit your need.
