Should I be worried?
Okay, it took a little more time than that for them to arrive

Materials: Styrofoam cubes (2 7/8 in.), glue, posterboard, and to finish them off, shiny adhesive vinyl specialty paper (like contact paper) that I found in the scrapbooking section of Jo-Ann's. Also, headless cat. Sorry, Ash, I was not focusing on you in this pic!

To make the cubes smoother before putting contact paper on them, I dress them in posterboard. This involves lots of careful measuring, that always seems to almost work.

Cardboard coated cubes. I could be done now, but decide to spend another four hours doing more careful measuring to make them look more shiny and mysterious.

Here is the pattern for the outer shell covering. I adapted it in later iterations to have less fold-over since the folds are noticeable. It took a little while to remove the backing on the middle square after cutting the contact paper out, and there were some mistakes, but overall it worked as I'd thought it would

Sat the cube on the middle square and then I was able to peel off the edges one by one to put the outer layer on smoothly.

Putting on the outer layer. Yes, in my awesome purple Halloween candy corn pajama pants.

Two finished cubes next to the two cardboard-only ones. I think it's an improvement!

Still life with cubes.
So that's cubes 101. I started with 2 7/8 by 2 7/8 by 2 7/8 and after coating them ended up with 3x3x3 inch cubes. They might be a little bigger than the ones on the show, but I am still pretty satisfied with them.
