Inspired by a YouTube video I saw on awesome Numberphile channel about how to draw hitomezashi stitch patterns I decided to recreate them in Python with the aid of the Tkinter Canvas element. The pattern is quite simple and is an example of simple rules creating complex patterns, which I have an interest in.
The idea behind hitomezashi stitch patterns is to take two sets of numbers and draw lines on a grid. One set of numbers is the horizontal and one set is the vertical lines of the grid. The lines drawn are dashed but the key difference is that each start of the line is offset from the start depending on a certain factor. In the video Ayliean MacDonald uses letters of a phrase and offsets the start of the line if the letter is a vowel. She also uses the numbers of pi and offsets if the line if the number is odd.
