I got this drawer box from something called the Practical Origami Convention.  I didn’t actually attend the convention, but happened to access the models later, and picked this one out to fold.  I have to imagine that there are a bunch of origamists making “practical” designs like tiny chairs to sit on, and tiny tables to hold tiny flowers.  (I’m joking, I know that practical origami has a lot of emphasis on boxes and envelopes.)

I can’t remember how many sheets this needed, but it was over 10.  Each drawer is a separate sheet, with another sheet to be used as lining.  The cabinet box (I had to look up what this part of the drawer is called) is made of 4 pieces, or maybe more?

Now obviously there’s a lot of origami that stretches what you would think is possible with a single sheet.  But other designs are more sheet-maximalist, with multiple distinct units working together.  There’s some complexity in that; you need to make the sizes match, accounting for the thickness of the paper, and some units need to be firmly attached to each other.
