Geometric Crochet Sunrise

Our moms have created a new piece of geometric crochet sculpture art! This time, they have made it in the colors of the sunrise!


This piece of geometric crochet is made from acrylic yarn, and crocheted using the pattern for a hyperbolic plane (and an H hook). Each row has more stitches than the last, by N=4, such that every 4th single crochet has 2 stitches in the same stitch.
The number of yellow (315) > orange (274) > red (235) stitches. This pattern is based on the work of Daina Taimina of Cornell University and this article in Science News.



You may need your sunglasses when you see this item in the Etsy shop!

Newest Geometric Crochet!

Here is Mom's newest Geometric Crochet sculpture! This one was made using a much tighter configuration (rho=2), such that you add a stitch every other stitch. That makes for a very quickly increasing hyperbolic plane. You can compare this one to "Floral Reef" in a previous post.Mom says: "This piece I'm calling "Brain Coral" because the ripples remind me both of coral and of brains. This one is tight enough that you can wear it on your wrist as an interesting cuff or bracelet. Our cats can wear it as a fashionable lion-style collar. :) You can even make it look like a weird monster face!"

This piece is currently for sale in Mom's Etsy shop. Go check it out! :) http://lazycat.etsy.com.

Mom's turn at Geometry and Crochet

We're going to let Mom explain this one....


I was inspired by a thread in the Etsy forums http://www.etsy.com/forums_thread.php?thread_id=5042733 to try to make some "geometric" crochet. I started out with the hyperbolic plane, where you add a stitch ever N stitches such that the surface area of the plane expands with each row. It starts out as a curly-q and then can be twisted to form all sorts of cool shapes. Here are the beginnings of my first attempts:


H-hook, N=4


F-hook, N=2



I hope to add more rows and more colors to these as they grow.


Here is the original article (love the pictures in this one)

and here are crude instructions (I'm going for rho=4cm)

I'll come back and post more pictures as this progresses. If anyone is excited about purchasing it, use the email link to the left. Please feel free to leave any comments below.

And, I promised I would put something in about the cats, so here are Nemo and Mittens being super cuddly:
