For this project I (along with my kids) made a full size Lego man made out of Lego. We made the head out of yellow Lego (the interior which can’t be seen wasn’t yellow though). For the rest of the body we just used whatever Lego we had available as we didn’t have the Lego sorted by color. I didn’t have any good Lego to serve as the hands, so the arms and hands are a little clunky. Overall I am pretty happy with how it turned out!
Here is a video summarizing the Lego man and how he was built.
