One day, C. went on a trip abroad and left me a message on the fridge which inspired me to make her a heart of Lego. The first version was a two-dimensional heart. But hold on, Lego is a three-dimensional thing.
Build it yourself
If you need some help to build the 3D heart, then download the building instructions here. The zip contains an XL sheet with the list of pieces, a small website that shows you how to construct the heart and the design of the heart in LEGO Digital Designer format. You can download the program here (for free)
