The challenges all rose from the concrete. I couldn't get the first stool out of the bucket and had to hammer on the bucket until the cement started to crumble. I added about an inch too much to the second stool, so that it was top-heavy and convinced me it would tip over and crush someone's foot

Since I was just pouring a little concrete out of the bag each time and not using it all at once, each stool has a slightly different ratio of gravel to cement. I tried to sand the edges of some of the voids near the sides or tops of the stools to prevent clothing from snagging on it, but this is just a Sisyphean task of sanding, having it crumble a little, exposing more cement edges, and then sanding again.
The concept is sound, but for it to be actually useful I need to invest in countertop-grade concrete and figure out a method of removing the stool from the bucket easily and safely.
