If you have forgotton, a binary tree is what you get if you branch off two times from each branch, then again, then again – think of a tree trunk that divides into 2 main parts, then each main part divides into 2, then each of those divides into 2 etc. You can also get tertiary trees where all the ends divide into three but for the moment I’m playing with binary trees.
Anyway I was kept up all night wondering what happens if you crochet a binary tree.
I started off with a circle but discovered that if you keep adding 2 stitches to the stitch below you end up with a bigger circle.
So then I chained 5 and double crocheted twice into each stitch on the row below for 5 rows. This is what you get, it looks like coral to me!
It still makes a circle if you roll it up.
