Hyperbolic Shrubbery

The Hyperbolic Crochet Coral Reef was definitely one of the inspirations for this project. I’ve long been fascinated by hyperbolic crochet: I had the opportunity to add a small piece to the UK Reef way back in 2008, and I created and ran the Hyperbolic Crochet Community Project at Worldcon 75 in Helsinki in 2017.

The charm of hyperbolic crochet is that you can create organic forms using a very simple set of instructions. If you can create corals, why not leafy things as well? Here’s my result of trying to make a bit of shrubbery:

For this, I made a fairly long chain and then used single crochet (US term)/double crochet (UK term) working back and forth. The ruffling is created by increasing regularly at a fairly high rate, I increased every second stitch here, so two stitches in one row become three in the next. In the last couple of rows, I added some multicolour thread to the fairly light green base yarn for some visual interest. Doesn’t look like much, but makes exactly the right impression when installed:

To achieve this effect, I laid the base chain down in tight curves, forcing the ruffle to turn into itself and creating an impassable piece of shrubbery. I’m currently fixing all the bits and pieces to the platform using glass-head pins, in order to be able to move them around and rearrange them easily.

A hint on size: We’re going for trees with a maximum height of 20cm, assuming that would be about 20 metres in reality. So the distance between the base chain and the last row should be at most about 5 cm (2 inches), which would make a substantial stand of bushes around 5 metres tall.
