December brought no shortage of great LEGO content from around the globe! Here at BrickNerd, we started the month by converting the LEGO Ideas steamboat into Master Chen’s ferry, had two talented teams compete to turn a retail set into a GBC module, looked at an innovative way to convert light bricks into Christmas tree lights, and found that new elements sometimes warrant revisiting an excellent MOC to make it even better!

We looked at the ever-growing array of costumed minifigs, revisited a hot drink stand MOC, saw the detailed inspiration and planning going into wonderful Spiderman inspired MOCs, and provided instructions to build your own microscale train. We learned how a group LEGO build can be a catalyst for something bigger than the completed model, and looked at how annual MOC collages can be fun historical references as well as a means to see building skill progression.

In fact, we’ve published so many interesting articles in December that we’ve included an interactive calendar of them at the bottom of this post, so you can make sure you haven’t missed a thing. But there are many more fascinating stories to be told from within the LEGO community, so here are some of the best LEGO articles and videos that caught our contributors’ attention throughout the month of December. We applaud the effort that went into each of these features, so click on the headlines or photos to head to each story or video. They are well worth your time!
