about the artist

Manca Ahlin wove Gymlacium using traditional bobbin lace techniques that she learned as a child in Slovenia.

“When an old space with an industrial cast iron structure, that used to be a library, collides with handmade bobbin lace, that used to be made as a benign little doily, you find a wondrous space that is a three-dimensional fiber labyrinth of numerous pieces, connected into a giant interactive network. From the initial elements (bridge, trees, ladders, hills, waves, hammocks), the structure constantly grew and with time (including a global pandemic lockdown) the pieces expanded organically, connecting into a neural network- like our brains or nature taking over abandoned sites.

Through these connections, every action will cause a reaction somewhere else and hopefully remind you that you are not alone in the world, so whatever you do, it will affect someone or something else.”
