First order of business: making a star, of course; then photographing it without dropping my iPhone in the wet concrete.
Once there were enough glass fragments all over, it's time to trowel them in. The concrete will then be cured over the course of a week.
Update: It's over a week later! The counters were polished, and this is what they look like! All that's left to do are minor touchups and applying a sealant. Doesn't this look awesome?
