Engineering the felt Cactus Garden

The ribs of cacti are either fleshy branch like sections of the main trunk or perpendicular vanes that sit proud of the trunk. This structure is a survival mechanism, it allows them to swell and shrink, to manage dramatic rainfall fluctuations without cracking or wilting.  Spines are both a protection mechanism, they prevent predators from munching on the fleshy part of the plant, give shade, impede water loss and insulate against the cold.  So it was important that I had a similar structure in the felt – I solved this with multi- ribbed resists and vane like protrusions encased in a final layering of wool.
