This journal explores how colour, light, and geometry shape the way we feel in the spaces we live with every day. These pieces are not theoretical essays, and they are not decorative tips. They are written to make something familiar suddenly clearer. Why a room feels calm but unfinished. Why another feels impressive but distant. Why a small change can quietly transform how a space supports you. Hard Edge glass works with these questions at their emotional root, not by adding more, but by tuning what is already there.
