A light box.
I put a drawing in place, and the cloth above the drawing.
The triangles are waiting side by side, meticulously organized.
I start working: The first piece is critical and should be centered.
I take a deep breath and glue it.
Another piece and yet another join the previous, the spacing is important and so are the edges.
Each triangle gets its deserved attention and then the magic happens: a figure takes shape.
Step by step the cloth is transformed into a plane of triangles, marking varied folding options.
I pick up the opportunity and start folding: edges are aligned, vertices touch each other.
I play with the options until structure starts forming, volume is created, box shaped envelopes emerge.
The shapeless cloth becomes a sheet with folding potential, the sheet becomes a bag with real volume.
