December Adventure Log

December Adventure was started by Eli_oat at Oatmeal. I love seeing what others do this month - here is a log of logs.

This December, I plan to make a generative quilt, play with origami, doodle some mossy mandalas, set up next year's journal, and who knows what else. This post is the log where I will update and share my adventure.

Day 1 - Pick a Quilt

I have a jellyroll of 4-5 tones of fabric, which I hope to make a small quilt with. Using randomness and p5.js, I picked a quilt. There is both a random block generator and a random rotation pattern that I used to get this. I started the code last week and plan to clean it up to share over the month. There are a lot of features and options I'd like to add. My mom looked through the patterns with me, and we had fun looking at ones that sometimes seemed translucent, woven, or jittery.

Here is a snapshot:

There is one block (and its reflection). The rotation pattern that wraps is 0 degrees, 0 degrees, then 270 degrees of the reflected block - so a 2:1 ratio of blocks.

A light vertical stripe, then a stripe with a black square and light grey strip, the a dark grey strip and lighter grey square, then a black strip

reversed block with the black stripe on the left and bright stripe on the right mid tones in the middle withsquares from the light and dark.

I am not sure how much fabric I have - because I haven't done the math yet, but I am happy with various sizes of the 0-0-270R pattern with these blocks. Here are some different sizes using that ratio/pattern.

I made three blocks tonight:

Three jellyroll blocks with fabric that has a mix of flowers, stars, plus signs, and mathematical curves. Two blocks are the same, the other is reflected.
